Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for mixing compound feed for animals and adding molasses, fats and oils, etc. for the purpose of supplementing calories or imparting palatability.

Traditionally, supplementary calories are supplied to animal feed,
Or, for the purpose of imparting palatability, a method of adding molasses (molasses), fats and oils, etc. is generally carried out, but molasses has a high viscosity and it is difficult to add it uniformly.

In other words, molasses generally has a viscosity of c-p (centipoise).
5,000 to 10,000, which is extremely high, making it difficult to spray finely with a single-fluid nozzle.Also, it is possible to spray with a two-fluid nozzle using compressed air, but the amount of compressed air required for 1 kg of molasses quantity is at least 5001
The above is also required, resulting in considerably large power consumption and a large number of nozzles.

Therefore, in the feed industry, the production process is generally carried out in accordance with the flow sheet shown in FIG.

That is, after weighing the blended raw materials in the blending tank 1 using a weighing machine 2 so as to have a predetermined ratio, the receiver passes through a hopper 3, a conveyor 4, a packet elevator 5, and a service tank 6, and then mixes and blends them using a ribbon mixer 7, etc. Then, the receiver is once dropped into the hopper 8, and sent to the high-speed continuous molasses mixer 11 via the powder flow rate detector 10 by the conveyor 9, and in this high-speed continuous molasses mixer 11, the flow rate is A total of 14 molasses additions are made via the switching valve 15.

This high-speed continuous molasses mixer 11, as shown in FIG.
A beater (concave plate) is attached to the rotating shaft 16 that receives the rotation of the drive source.
Stirring rods 18 with 17 attachments are installed in a staggered arrangement, and are normally rotated at 1000 to 120 Or, pom. The resulting small lumps or large lumps (those that gradually became larger due to the adhesion of the powder blended raw materials to the droplets of molasses) are crushed by the Peter 17 of the stirring rod 18, and
This has the effect of uniformly dispersing molasses in the blended raw materials.

This high-speed continuous molasses mixer 11 is used for mixing blends (the term "mix" is used for mixing solid substances such as powders, and the term "blend" is used for mixing different types of substances such as liquids).

(hereinafter the same)), as described above, a two-step manufacturing method including mixing and blending using the ribbon mixer 7 is adopted.

In addition, in the high-speed continuous molasses mixer 11, addition of molasses by weight is technically very difficult in combination with continuous weight measurement of raw material powder, and therefore, molasses is generally added by volume.

Note that this high-speed continuous molasses mixer 11 has the disadvantage that it cannot be used when the raw material is easily crushed, such as flakes or pellets, because it requires high-speed rotation.

In addition to the above, a vertical continuous mixer may be used instead of the horizontal mixer described above.

On the other hand, in order to avoid the above-mentioned two-step manufacturing process, a ribbon mixer, which has been evaluated for its performance as a conventional blending mixer, is used, a space box for adding molasses is installed above it, and compressed air as described above is used. There are devices on the market that have a one-fluid molasses spray nozzle attached to a box part, and the mixed raw materials are dropped into the mixer. The drawback is that it requires a large number of nozzles and consumes excessive power.

In view of these conventional drawbacks, the present invention (a) performs mixing and blending and addition of molasses using the same device, that is, in one step.

(b) The compounding and blending equipment is a conventional batch mixer with one ribbon mixer, which has good compounding and blending performance.

(S1) The molasses spray nozzle is an energy-saving type that uses molasses fluid and does not use compressed air.

2) In order to add the amount of molasses by weight measurement,
A batch mixer is used for blending.

(e) The lifting machine for mixing the flaky or pellet-like forming raw material and the mash-like powder raw material and for recycling shall be rotated at a low speed to the extent possible.

This was created to satisfy the above conditions (a) to (w), and its purpose is to uniformly blend the mixed molasses of various animal compound raw materials in one step, and to measure the weight of the molasses. It is an object of the present invention to provide a gravimetric molasses blender that is capable of blending even when some of the blended raw materials are molded products in the form of flakes or pellets.

For this purpose, the present invention provides a batch mixer with effective blending performance and a molasses addition device in the same device, and each mixed raw material is weighed in advance with a weighing machine and then mixed into the batch mixer. It is characterized by a so-called recycling type mechanism, in which a part of the molasses is continuously transferred to the molasses addition equipment while being mixed in the molasses mixer, and then returned to the batch mixer while adding molasses (molasses). A mixing tank having a raw material input port and a blended product discharge port that can be opened and closed; a ribbon mixer blade that is rotatably supported in the mixing tank and mixes and blends the input raw materials; and mixing by the ribbon mixer blade.
