Forming equipment for producing dried rolled bean curd under normal-pressure steam conditions

Abstract

The invention relates to forming equipment for producing dried rolled bean curd under normal-pressure steam conditions. The forming equipment comprises a back-burning type normal-pressure overheatingsteam oven and dried rolled bean curd forming devices, wherein the back-burning type normal-pressure overheating steam oven is used for providing steam for the dried rolled bean curd forming devices for heated forming. By the back-burning type normal-pressure overheating steam oven, generated saturated steam is continuously heated with heat of fume, overheated steam is generated in a normal-pressure state and then is applied to forming of the dried rolled bean curd, the efficiency of forming is high, and meanwhile, the requirements of pulp cooking and baking of a dried rolled bean curd production process on heat supply can also be met; the back-burning type normal-pressure overheating steam oven generates the overheated steam in the normal-pressure state, the steam supply of a plurality ofdried rolled bean curd forming devices can be met, and compared with the traditional normal-pressure steam ovens, the heat efficiency is high and the energy consumption is low; and with respect to pressure-bearing steam boilers, potential safety hazards are less, the technical requirements on design, manufacturing and use are relatively low, customer use is safer and more convenient, and use andoperating costs are lower.

Description

technical field [0001] The invention relates to the technical field of bean curd stick processing equipment, in particular to bean curd stick production and molding equipment under atmospheric steam conditions. Background technique [0002] Yuba, also known as yuba or bean curd skin, is a solidified film on the surface of boiled soybean milk, which can be eaten fresh or dried. Yuba originated in the Tang Dynasty and has a history of more than a thousand years. It is very popular among Chinese people. A traditional food, the process of which is peeling—soaking—mixing—refining—filtering to remove slag—boiling pulp—extracting bean curd sticks—drying to obtain bean curd stick products. Yuba is a high-quality soy product that is rich in nutrition and can provide balanced energy for the human body. The nutrient density of yuba is higher, rich in nutrients, rich in VE, unsaturated fatty acids, isopropyl ketone, lecithin and other functional ingredients, free of cholesterol, regula...

AI Technical Summary

Problems solved by technology

[0005] 1) There is a combustion chamber at the front end of the tunnel-type fire channel, and the end is connected with the chimney. The flame and high-temperature flue gas generated by the combustion run through the bottom of the entire steam generation tank under the action of self-absorption of the chimney. The long fire tunnel causes damage to the yuba. The heating of the forming tank is not uniform, which causes the temperature difference of the bean curd stick forming tank to be too large. When the temperature is too high, the bottom of the forming tank will be sticky and burnt; Yield and quality of yuba

[0006] 2) Due to the large flame and high temperature of the high-temperature flue gas at the front end of the tunnel-type fire channel, the front end of the steam generating tank is locally heated, which is easy to cause deformation and affect the service life

[0007] 3) The fuel in the tunnel-type flue is not fully burned, and black smoke is emitted, which is self-absorbed and discharged directly into the atmosphere through the tall chimney, causing pollution to the environment; the fuel heat conversion efficiency is low, the fuel loss is large, and the use cost is high

The flue gas treatment device supporting the pressurized steam boiler has a large investment and high operating cost

[0010] 2) The pressurized steam boiler is a special equipment, and the operators must pass the special training and work with a certificate

[0011] 3) Potential safety hazards are likely to occur during the use of pressure-bearing steam boilers. If the operation and use of the equipment are not strictly followed and the maintenance of the equipment is not in place, safety accidents are likely to occur, resulting in equipment damage and personal injury

The flue gas treatment device supporting the atmospheric pressure steam generator has a large investment and high operating cost

[0014] 2) The saturated steam generated by the atmospheric pressure steam generator enters the steam tank through the steam pipe and evenly disperses into the cavity, and exchanges heat with the bottom of the bean curd stick forming tank. After the saturated steam enters the steam tank, the steam space expands, the pressure drops, and After the heat exchange, the temperature of the steam in the steam tank drops, the temperature of the steam in the tank is lower than the condensation temperature of the steam, and condensed water is generated, the heat utilization efficiency of the steam is low, and it is difficult to meet the normal working temperature required for the bean curd stick forming; in order to meet the bean curd stick forming The required normal working temperature requires the input of a large amount of saturated steam for supplementary heating, resulting in a large amount of steam usage, high energy consumption, and high production costs
