Put the ground soy milk into the shaker by gravity or use a submersible pump to filter the pulp, filter it in the first filter bag of the electric low-speed shaker, fill the first bag to 4--5% full, and then put the ground soy milk. Pour it into the second filter bag for filtration, and fill it to 4-5% full, and so on for the third and fourth filter bags. The filtered thick slurry is directly poured into (or flows into) the yuba pot. When the thick slurry of the first bag is filtered very slowly, pour an appropriate amount of tap water into it, stir the bean dregs by hand, filter, and filter out more The thick soy milk is also poured into the yuba pot. When the second, third and Nth times are poured into the tap water (or use a tap water pipe ≥ 1.2 inches) to wash the residue, part of the filtered thin soy milk water is poured into the soaking bean pool. It is used to grind the pulp, and the rest is poured into the next filter bag to wash the thick bean dregs.

1. Raw pulp yuba filter pulp:

Put the ground soy milk into the shaker by gravity or use a submersible pump to filter the pulp, filter it in the first filter bag of the electric low-speed shaker, fill the first bag to 4--5% full, and then put the ground soy milk. Pour it into the second filter bag for filtration, and fill it to 4-5% full, and so on for the third and fourth filter bags. The filtered thick slurry is directly poured into (or flows into) the yuba pot. When the thick slurry of the first bag is filtered very slowly, pour an appropriate amount of tap water into it, stir the bean dregs by hand, filter, and filter out more The thick soy milk is also poured into the yuba pot. When the second, third and Nth times are poured into the tap water (or use a tap water pipe ≥ 1.2 inches) to wash the residue, part of the filtered thin soy milk water is poured into the soaking bean pool. It is used to grind the pulp, and the rest is poured into the next filter bag to wash the thick bean dregs. The thicker soy milk is also directly poured into the yuba pot. Then, the thinner soy milk water is filtered out, and part of it is poured into the soaking bean pool. It is used to grind soy milk, and the rest is poured into the next filter bag to wash thick soy dregs, and so on. , when no water flows out, put the bean dregs in a plastic textile bag.

Second, cooked pulp yuba filter pulp:

Put the ground soy milk into the shaker by gravity or use a submersible pump to filter the slurry, filter it in the first filter bag of the electric low-speed shaker, and fill the first bag to 5-60% full, and then put the ground soy milk. Pour it into the second filter bag for filtration, and fill it to 5-6% full, and so on for the third and fourth filter bags. The concentrated soy milk filtered out of each filter bag is temporarily stored in the pulp filter tank. When there is almost no soy milk filtered out of the first filter bag, put some tap water into the filter bag, stir the bean dregs by hand, filter, and control the concentration of the thick soy milk in the filter tank to 8-9%, and then use diving The pump is pumped to the temporary storage bucket for thick pulp next to the slurry boiler, and by analogy, the thick pulp in the pulp filter tanks of the 2nd, 3rd and 4th filter bags is also pumped to the first one containing thick pulp. Then put tap water into each filter bag to loosen the bean dregs by hand and filter. At this time, the thin soy milk is also temporarily stored in the filter tank. When the filter tank is full, it is pumped to the side of the cooking pot. the temporary storage bucket for thin soy milk. And so on, wash the bean dregs thoroughly, and then pump the final dregs water into the temporary storage bucket for the dregs. Thick soy milk, thin soy milk and slag washing water should be boiled separately in the pulping pot.

Three, pick yuba method:

1. To pick the flat bamboo, use the index finger and thumb of the left hand (the nails should be cut short, otherwise it will be unsanitary and the film will be broken) to pinch the film in the middle of the side closest to you, and remove the pulp from the pulp. When the surface is lifted by a third, the right hand quickly supports the middle of the yuba with the fruit knife or the face of the thin wood slice (the left hand is released at the same time), and when it is lifted two-thirds from the pulp surface, the left hand will just leave the The film on the left side of the pulp surface is folded to the right, and then placed on a bamboo pole. The shape of the flat bamboo is a flat strip of yuba with a wider and thinner part hanging on the bamboo pole and a narrower end with some overlapping films.

2. How to pick the round hollow yuba: Use the index finger and thumb of the right hand to pinch the middle of the side of the film closest to you, lift the film away from the pulp surface, and gently rotate it clockwise to make the film Fold it into a hollow strip. At the same time, use the left index finger and thumb to pinch the yuba film that has not been gathered on the left side in a counterclockwise direction to wrap the hollow yuba strip that is rotating clockwise, so that the two ends of the yuba are roughly the same as the middle. Thick, but slightly pointed at both ends, then hung on a bamboo pole. When producing solid round yuba in places such as Fujian and Jiangxi, there is no need to rotate the yuba skin with the right hand, just lift it with the right hand and gently squeeze the unsatisfactory part with the left hand.

3. Picking method of three-sided yuba: Use a stainless steel strip of €4mm to shape a tool (the width of the part that sinks into the pulp bottom is 2cm smaller than the width of the wooden frame). Press the film with the belly of the left thumb lightly to push a seam open, hold the tool in the right hand, put down the tool on the edge of the film closest to you, move it to the middle of the film under the film against the bottom of the pot, and lift the tool. When the film is folded and hung on the stainless steel bar, then hang the film on the bamboo pole, the left index finger and thumb gently pinch the left end of the yuba skin with the tool, and the right hand quickly pulls out the tool, when the action is too slow, the yuba skin will The sticky tool cannot be pulled out. Note: Before lifting the film, make a slash on the wooden frame around each grid with a fruit knife or thin wood chips, so that the yuba skin does not stick to the wooden frame and break the film. After picking one or a piece of yuba Afterwards, if there is foam on the pulp surface, use a fruit knife or thin wood chips to gently scrape it on the wooden frame, otherwise the yuba you pick next time is easy to break or rot, and the film is too thin to pick it up. Also breakable or perishable.

4. Raw pulp process production

Fill the bean curd pot with the filtered soy milk at one time, and there is no problem of adding milk in the middle. When the soymilk in the yuba pot is thicker and the color is darker, follow the production method described in the "Instructions for the Use of Yuba Additives". Not repeated here.

5. The method of producing yuba by mixing raw and cooked pulp:

Make the effective volume (that is, 70% full) of the pulp cooking pot the same as the effective volume (ie, 80% full capacity) of a bean curd pot. The effective volume of the pulp pot is the same as the effective volume of a bean curd pot). The filtered soy milk is boiled with steam from an industrial boiler or by burning wood or coal. After adding the first yuba additive, pour it all into a yuba pot to keep the skin warm and pick the yuba, and then the next operation method is the same as the raw pulp method. This method not only overcomes the shortcomings of the raw pulp process, but also overcomes the shortcomings of the raw pulp process. It also overcomes the shortcomings of large workload and labor in the cooked pulp process.
