Description

Detailed Description of the Invention The present invention provides a boiling pot with both ends closed on the machine frame, the outer peripheral surface of the pot is double walled, a heating chamber is formed between both ends, and a heated steam supply pipe is installed inside the pot. This relates to a continuous tofu manufacturing apparatus in which the number of steam outlets of the supply pipe is larger at the starting end and middle of the pot and smaller at the terminal end, and the number of steam outlets is smaller at the terminal end. By boiling the soup with steam from the beginning to the middle, reducing the amount of steam at the end and switching to steaming at the end, we can mass produce high-quality products with a high amount of protein extraction. The purpose is to

To explain the embodiment of the present invention shown in the drawings, the machine frame 1
A U-shaped horizontal boiling pot 2 is provided, the top surface of the pot 2 is closed with a lid 3, and a cylinder 4 open to the atmosphere is provided.

A screw conveyor 5 is disposed inside this pot 2, and a plurality of steam supply pipes 6 are disposed in the bottom part in the longitudinal direction. , heating chamber 9 between 8
It forms the As shown in FIG. 3, the number of steam outlets 10 in the supply pipe 6 is increased from the starting end to the middle of the pot 2 (the interval between the outlets 10, 10 is small).
, fewer holes are made at the terminal end (the spacing between the ejection ports 1 and 10 is large) to adjust the amount of heated steam ejected.

Furthermore, as shown in Fig. 4, the cylindrical vertical kettle 2 does not have a screw conveyor, but a pump 12 is installed in the raw material supply pipe 11 connected to the lower end (starting end), and the power of the pump 12 raises the raw material to the upper end. A discharge pipe 13 that is open to the atmosphere is provided at the end (terminus). In this vertical boiler 2, a plurality of steam supply pipes 6 are provided horizontally, and from the starting end to the middle, the number of supply pipes 6 is small and the distance between them is small, and at the terminal end, the number of supply pipes 6 is small and the distance between them is large. Therefore, the number of steam jet ports 10 is large at the starting end and in the middle, and is small at the terminal end. The heating chamber 9 is provided with a heated steam supply pipe 14 and its discharge pipe 15 at the starting end and the ending end of the heating chamber 9, so that the heating chamber 9 is filled with heated steam. In addition, what is indicated by 16 in the figure is a temperature sensor, 1
7 is a driving sprocket of the screw conveyor 5, 18 is its driving chain, 19 is a steam trap, 20 is an opening/closing cock, 21 is a jam plate in FIG. 4, and 22 is a partition wall of the heating chamber 9. Therefore, the pump 12 is operated to supply the raw material from the supply pipe 11 to the starting end of the pot 2, and while slowly moving it from the starting end to the terminal end, the adjusted heated steam is introduced into the heating chamber 9. When the pot 2 is filled with radiant heat s and heated steam is ejected from the spout 10 of the supply pipe 6,
The supplied porridge is boiled at a temperature close to 100° C. by a large amount of heated steam from the beginning to the middle, and becomes a boiling porridge.

Then, when moving to the terminal end, the amount of steam decreases to about 1/11 of the starting end and the middle, and the regulated heated steam radiant heat of the heating chamber 9 creates a complete and complete stream of steam heat from the jet nozzle 10 and the heating chamber 9. After steaming is performed, the rice is discharged from the discharge pipe 13 and continuously flows to the next process. Conventionally, in the production of tofu using a boiling pot, only the first step was carried out using 100% heating steam from the start of boiling until the end of boiling, which was what was called a slow cooking process, making it difficult to obtain a high-quality product with a large amount of protein extracted, especially in continuous production. It has been difficult to improve the quality of pot-based products.

The present invention has been made in view of the above-mentioned defects, and since the present invention is constructed as described above, the first step of boiling the raw food with heated high-temperature steam and the above-mentioned heated steam are performed at the starting end and middle of the pot 2. The second step of steaming and reducing the amount of soybean protein can be performed continuously to prevent overcooking caused by the first step, and complete steaming is performed in the second step to prevent destruction of soybean protein and extract the amount of protein. It improves tofu yield, firmness, gloss and fineness of tofu, has good texture, sweetness and shelf life, requires a small amount of coagulant, and is free from the fishy odor and taste characteristic of raw soybeans. It is possible to continuously mass-produce high-quality tofu.
