Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a continuous automatic manufacturing method for fried silk and an apparatus therefor.

Conventional technology and its problems Conventionally, to produce fried tofu, bittern is injected into soy milk and bittern is coagulated to produce tofu, then this tofu is broken and stirred to destroy it, and then this is further broken down. Adjust to the appropriate thickness and shape for deep-frying.

That is, crushed tofu is placed in a mold and dehydrated under pressure.

This tofu has a high water content and cannot be fried, so it is dehydrated to a moisture content suitable for deep-frying. This is then cut and shaped into the required size and fed to a fryer to make deep-fried tofu and thin-fried tofu.

Therefore, the fried tofu produced by this method is chewy and hard because the tofu is crushed.

In order to improve the taste, silken tofu that is fried as it is, ie silkage, has recently become popular, but silken tofu is softer and more easily broken than firm tofu. For this reason, after producing silken tofu, workers carefully cut each tofu by hand into sizes suitable for silkage, arrange them on a cloth, and then separate them on top of the silken tofu. The cloths are layered so that the tofu sandwiched between the upper and lower cloths is dehydrated by the water absorption properties of the cloths. The water-absorbed cloth is wrung out several times and this process is repeated until the desired moisture content is reached. Thereafter, this is put into a deep-fried tofu machine to make the desired deep-fried silk. For this reason, the manufacturing process involves a lot of manual work, resulting in high manufacturing costs and inefficiency.

The purpose of the present invention is to continuously and automatically produce this fragile silken tofu without destroying it and without requiring any manual work.

Means to solve the problem A coagulation process involves continuously manufacturing silken tofu by injecting an appropriate amount of coagulant into soy milk obtained by squeezing soybeans and supplying stirred tofu raw materials, and a process adjacent to this coagulation process. There is a cutting and separating step in which the coagulated tofu is cut into sizes suitable for silk-frying in the vertical and horizontal directions, and each piece is appropriately spaced from each other. A draining process in which water is automatically and continuously removed by the weight of the upper belt by synchronously driving both the upper and lower belts, which are arranged above and below and equipped with dewatering rolls. and the frying process of an automatic frying machine adjacent to this are arranged in series to automatically cut the continuously produced silken tofu, and to continuously dewater it using a water-absorbing cloth belt. To hygienically and automatically produce silk fried rice with good flavor without destroying tofu.

Embodiments Next, the present invention will be explained with reference to embodiments shown in the drawings. In the figure, 1 is a continuous tofu manufacturing machine in which a large number of partitions 1b, which serve as coagulation tanks, are protruded from an endless belt 1a at regular pitches. The required amount of soymilk and an appropriate amount of coagulant (bitternard), etc. are placed in each coagulation tank formed between the partition 1b and the long partition plate 1c. is injected and stirred. When this partition 1b is moved for 10 to 30 minutes or more, the soybean milk coagulates and silken tofu is produced. A cutting and separating step 2 is adjacent to the end of this coagulation step. In this process, the vertical blade 2b and the blade 2a are cut into a size suitable for making the manufactured silken tofu.
The pieces are cut horizontally and separated one by one with appropriate spacing to prevent them from joining together during the frying process. This is a separator plate 2 attached to a fixed vertical blade 2b.
c is provided so that when the tofu cut by the vertical blade 2b is moved, it is naturally separated by this separating plate. This movement is carried out either by creating a head difference between the coagulation process and the next draining process such that the draining process side is lower, or by forcibly using a belt conveyor or the like.

The draining process is adjacent to the cutting and separating process, with a belt conveyor at the bottom for supporting and transporting each cut and separated silken tofu, and a belt made of water-absorbing fabric at the top opposite to this. An opposing draining device 3 is provided. This belt conveyor has a net conveyor 3c stretched between rollers 3a and 3b arranged at both ends, a water-absorbing cloth belt 3d disposed on the surface of this net conveyor, and one or both rollers are driven to move the conveyor. At the same time, the upper water-absorbing cloth belt 3e is used as a part of the dewatering roll 3 that pinches both the front and back surfaces to dewater the water-absorbing cloth belt 3e.
f, 3f, and this endless belt 3e passes from one to two belts on the lower belt conveyor.
With the above arrangement, the weight of the belt 3e allows it to be placed over the tofu placed on the lower belt conveyor, so that water is naturally absorbed and drained, and the belt 3e that has absorbed water is transferred to the lower belt conveyor. When continuously driven in synchronization with the dehydration roll, water can be dehydrated continuously.
Note that a dewatering tank is provided below the lower dewatering roller to discharge water to the outside.

In the frying process, a conventional continuous frying machine 4 is used, and the drained tofu is placed in the oil of a heated pot, is automatically fried, and is discharged from the pot.

The lower belt conveyor in the draining process is used to increase the conveyance speed in the coagulation process and automatically space the tofu apart in the feeding direction.

Effects of the Invention According to the present invention, the manufactured silken tofu can be cut into required sizes without the need for the conventional process of breaking soft and fragile silken tofu, shaping it again, and dehydrating it. After that, a special draining process is used to perform continuous and automatic draining and dehydration, making it possible to automatically and continuously produce silk-fried silk, as well as eliminating the manual labor required by workers compared to conventional methods, making it more hygienic and cheaper. It has the effect of being able to be manufactured.
