Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a grain processing device.

(Prior art) Conventional 1 A steam chamber is formed between the ascending part and the descending part of the endless belt made of a highly breathable material, and the back surface of the ascending part is the upper surface, and the endless belt is placed in the steam chamber. Steam pipes are provided in the left and right direction perpendicular to the direction of movement of the grains, and steam jet holes are formed in the steam pipes at predetermined intervals, so that steam is applied to the grains placed on the upper part of the endless transverse belt to cook rice. What has been done is publicly known.

(Problem to be solved by the invention) In the known method, when the width of the endless transverse belt is wide, the horizontal width of the steam chamber also becomes large, and the steam discharged from the steam pipe is biased in momentum between the source and the tip. There was a tendency for this to occur, resulting in uneven steaming and deterioration of quality.

(Means for solving the problem) The present invention aims to improve quality by preventing unevenness of steam, and takes the following technical measures.

That is, a steam chamber 2 is formed between the ascending part A and the descending part opening of the transverse endless belt 1 formed of a highly breathable material, and the back surface of the L-shaped part A is the upper surface. A steam pipe 4 is provided in the left-right direction perpendicular to the moving direction of the endless belt 1, and steam jet holes 3 are formed in the steam pipe 4 at predetermined intervals. In a device that cooks rice by applying steam, the steam pipe 4 is configured to supply steam from the left and right sides of the grain processing device.

(Summary of operation) Grain is transferred by the transverse endless belt 1 made of a material with high air permeability, and during this time the grain is transferred to the steam chamber 2 between the ascending part A and the descending part mouth.
Although it receives more steam supply.

Since steam is supplied to the steam pipe 4 from the left and right sides thereof, there are almost no spots.

(Example) An example of the present invention will be described with reference to the drawings. The grain processing apparatus 5 includes a primary steaming process A, a submerging process B, and a secondary steaming process C.

The second steaming step A includes a tank 7 having a shutter 6 at the bottom and steam supply means (not shown) for supplying saturated steam at about 100° C. at low pressure to the grains supplied in the tank 7. ing. The secondary steaming means may include a conveyor having ventilation holes and means for supplying steam to the grains on the conveyor.

Next, the submergence step B includes a water storage tank 10 having a water tank 8 capable of storing high-temperature water of about 85°C and a grain guide chamber 9 formed in the water tank 8, and a water storage tank 10 having a front surface on the outer peripheral surface of a cylindrical rotating body. It is equipped with a transfer device fill having a transfer plate having a visually rectangular shape. In addition, a large number of holes are provided in the lower portions of the left and right side walls of the grain guide chamber 9, and the holes are large enough to prevent grains from passing through, so that the high temperature water of 85° C. flows through the grain guide chamber 9 and is stored in a predetermined amount. Reference numeral 12 denotes a supply pipe that supplies hot water into the water tank 8. When a water flow sensor (not shown) provided in the water tank 8 detects a shortage of water, the water heater (not shown) is turned on until a predetermined amount is reached. It is configured to supply hot water. Reference numeral 13 denotes a 73% passage plate having a steam passage provided on the outer surface of the bottom wall of the wooden tank 8, with one end of the steam passage serving as a steam supply side and the other end serving as a steam discharge side. When it detects that the water temperature in the water tank 8 is below about 85°C, it is configured to guide high temperature steam to heat the bottom wall of the wooden tank 8 until the water temperature in the water tank 8 reaches about 85°C. ing.

Next, in the secondary steaming step C, the grains sent by the transfer device ll are loaded and conveyed, and an endless belt 1 having a large number of holes to prevent the grains from leaking, and an ascending part of the endless belt 1 are used. A plurality of steam chambers 2 are provided in a space formed between the bottom and the descending portion opening, and a plurality of steam chambers 2 are arranged in series in the moving direction of the endless band 1.

Further, the steam chamber 2 is formed into a box shape with its upper surface open, and its width in the left-right direction with respect to the grain conveyance direction is slightly larger than the width of the endless belt 1 in the left-right direction. The upper surface of each steam chamber 2 is in contact with or close to the lower surface of the ascending part 1 of the endless band 1, and the steam chambers 2 are arranged at predetermined intervals in the left and right direction with respect to the moving direction of the endless band 1. A steam pipe 4 having a plurality of steam ejection holes 3 arranged in the same direction is provided. Note that the steam jet hole 3 is provided at the bottom, and both ends of the steam pipe 4 are provided so as to be able to communicate with a steam purifier 15 that cleans high-temperature live steam sent from a steam generation source. The structure is such that low-pressure 100° C. saturated steam is fed from both the left and right sides of the steam chamber 2. Then, this saturated steam is heated to a high temperature (for example, about 120° C.) via a heating means (for example, a Nirefin heater, but not limited thereto). 16 is a steam pipe cover having a chevron-shaped upper part and an open lower part.

Reference numeral 17 denotes a rotating shaft that rotates in the direction of the arrow, and is arranged radially on the outer circumferential surface of this rotating shaft and at predetermined intervals in the left and right direction with respect to the conveying direction, so that the tip approaches the upper surface of the ascending part A when rotated. The stirring body is provided with a bar and is provided at the conveyance starting end of the endless belt 1. Note that the tip of the bar is bent in the transverse direction to form a bent portion to improve stirring performance.

This is the motor that is the driving source of 9.

Note that the grain processing apparatus 5 is provided with a cover 24 that can be freely overlooked on the left and right side walls and the ceiling, and an exhaust chamber provided in the ceiling so as to be able to communicate with an exhaust fan (not shown).
26 are provided.

(Effect of Example) Next, we will discuss the effect.

First, a predetermined amount of water at a predetermined temperature is supplied into the water tank 8 via the supply pipe 12 . Then, the water in the water tank 8 enters the grain guide chamber 9 through the hole, and the water surface becomes approximately the same height as the water surface in the water tank 8. At this time, this water temperature is measured by the water temperature sensor 14.
When it is detected that the temperature is below a predetermined temperature, steam is sent into the steam passage to heat the water through the bottom wall of the water tank 8.

Thereafter, when the water temperature reaches a predetermined temperature, the supply of steam is stopped.

Next, grains (hereinafter referred to as rice in this example) which have been previously soaked in a soaking tank (not shown) for a predetermined period of time (for example, one hour) are fed into the tank 7 for a predetermined amount of i through appropriate means, and Inside this tank 7, a temperature of about 100℃ was cleaned.
When the shutter 6 is opened, the rice in the tank 7 falls and is conveyed to the grain guide chamber 9 of the water storage tank 10 by the conveyor 18. Since soaked rice is supplied into the tank 7 by the above-mentioned means, a predetermined amount of soaked rice is always stored in the tank 7. Therefore, since the rice in the tank 7 gradually falls while being steamed, primary steaming can be performed continuously thereafter.

The rice sent into the grain guide chamber 9 is transferred to the transfer device 1.
1, it is transferred to the secondary steaming process C side, but during this time (
In the example, the sample is immersed in high-temperature water of about 85° C. for about 5 minutes to absorb water. The rice separated from the water and discharged from the water storage tank 10 onto the endless belt 1 is conveyed to the take-out side by the endless belt 1 and then collected by the conveyor 18. Approximately 120
It is steamed by being exposed to clean, low-pressure saturated steam that is heated to ℃ and floats up through the holes in the endless belt (the predetermined time for the next steaming is about 15 minutes), and this steam is passed through the steam pipe. Since the endless belt 1 is supplied from both left and right sides of the steam chamber 4 and is supplied into the steam chamber 2 from the steam jet holes 3, even if the conveyance width of the endless belt 1 becomes wide, it can be dispersed within the steam chamber 2.

Therefore, the filling time into the steam chamber 2 is shortened, which improves the steaming efficiency, and also prevents uneven steaming, thereby increasing the commercial value.

In addition, since the agitator 17 moves toward the take-out side at the starting end of the conveyance, it is possible to prevent a decrease in work efficiency due to stagnation of rice.
Furthermore, when the rice is gathered by the stirring body 17, it falls onto the endless belt 1 and is piled up higher than when it would otherwise be, so that the steam can flow better, preventing steam unevenness and improving the quality.

(Effect) Conventionally, a steam chamber is formed between the ascending part and the descending part of the transverse endless belt formed of a highly breathable material, and the back surface of the ascending part is the top surface, and the endless belt is placed in the steam chamber. Steam pipes are provided in the left and right direction perpendicular to the direction of movement of the grains, and steam jet holes are formed in the steam pipes at predetermined intervals, so that steam is applied to the grains placed on the upper part of the endless transverse belt to cook rice. What has been done is publicly known.

The known method is when the horizontal endless belt is wide.

The horizontal width of the steam chamber also became large, and the steam discharged from the steam pipes tended to have uneven momentum between the beginning and the end, which could lead to uneven steaming and a decline in quality.
! However, in the present invention, a steam chamber 2 is formed between the ascending section A and the descending section opening of the transverse endless belt 1 formed of a material with high air permeability, and the steam chamber 2 is formed with the back surface of the ascending section A as the upper surface. 2 was provided with steam pipes 4 extending in the left and right direction orthogonal to the direction of movement of the endless belt 1, steam jet holes 3 were formed in the steam pipes 4 at predetermined intervals, and the steam pipes 4 were placed on top of the transverse endless belt 1. In rice that is cooked by applying steam to grains,
Since the steam pipe 4 is configured to be used for processing grains so that steam is supplied from the left and right sides of the pipe 4, uneven cooking does not occur.

Since the width of the mouth and the endless belt 1 in the left and right direction can be increased, the efficiency of the steaming operation can be improved.

This effect is achieved.
