Embodiment

[0028] 1. Raw materials: soybeans, water, raw red gypsum, edible preservatives.

[0029] 2. Machinery and equipment, steam high-pressure hot press, stone mill, heating equipment, filter, vacuum machine, air dryer, dryer.

[0030] 3. Testing equipment: thermometer, acid-base detector, strength tester, moisture tester, electronic scale.

[0031] 4. Workshop requirements: dust-free workshop.

[0032] Process flow:

[0033] 1. Raw material processing. Take the soybeans, remove their shells and sieve them, wash them and soak them in a water tank for 4-5 hours in winter and 2.5-3 hours in summer. The soaking time must be well controlled, not too long, otherwise the pulp will be lost and tofu cannot be made.

[0034] 2. Put 250 grams of raw red gypsum (20-30 grams of gypsum per kilogram of soybeans) into the fire and roast. This is a key process. until it has just burned its heart). If the gypsum is too raw, it is not easy to use; if it is too cooked, not only can it not be mad...

Abstract

A production process for cutting tofu on a chopping board, comprising the following steps: 1) raw material treatment, soaking soybeans after peeling and washing; 2) gypsum roasting, putting raw red gypsum into fire for roasting; Take out the soaked soybeans, grind them with a certain proportion of water, grind the soybean milk, put it in a special cloth bag and squeeze it out; 4) Boil the pulp, pour the squeezed raw soybean milk into the pot to boil, and use The adjusted gypsum slurry is made into bean curd; 5) Make water tofu, after the bean curd is condensed, put it into the mold, heat-press and vacuum; 6) Air-dry and cool, completely cool the heat-formed tofu and air-dry; 7 ) Puncture the side of the tofu, use a needle to pierce the vacuum on the side of the tofu, and remove the moisture inside the tofu; 8) Drying and heating, heating and drying with a dryer; 9) Moisture test, use a moisture tester to detect the internal and surface humidity of the tofu; 10) Natural cooling completes all technological processes. The cutting board is environmentally friendly, saves wood, has high toughness, strong wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a production process of a chopping board, in particular to a production process of a chopping board made of tofu. Background technique [0002] The chopping boards produced and used in the market are almost all wood products or plastic products. With the gradual scarcity of domestic timber resources, wooden boards will be like disposable wooden chopsticks, which will cause a huge lack of resources. Foreign countries such as Japan either use metal chopsticks carried by each person, which is hygienic and resource-saving, or buy a large amount of wood from China. However, many places in China still use the destruction of important timber resources in exchange for little economic benefits. Plastic products are chemically synthesized products. Long-term cutting and chopping of dishes will inevitably be contaminated with some compounds. Long-term use may bring hidden dangers to health. It is better to use natural edible materials ...
