Pulp reflux system used for bean curd sheet production

Abstract

The invention discloses a pulp reflux system used for bean curd sheet production, and belongs to the field of bean curd sheet processing. The pulp reflux system used for the bean curd sheet production comprises a pulp refluxing pipe, a pulp feeding pipe, a pulp sucking pump and a buffering pipe; one end of the refluxing pipe is connected with a sheet condensing groove terminal of a bean curd sheet production device; one end of the pulp feeding pipe is connected to a pulp injecting end of the sheet condensing groove terminal of the bean curd sheet production device; the other end of the pulp refluxing pipe is connected with the other end of the pulp feeding pipe via the pulp sucking pump; one end of the buffering pipe is connected with the pulp refluxing pipe; and the other end of the buffering pipe crosses over the pulp sucking pump, and is directly connected with the pulp feeding pipe. A valve is arranged on the pulp refluxing pipe. Quick-opening valves are arranged at all pipe junctions and elbows of the pulp refluxing pipe, the pulp feeding pipe and the buffering pipe. The pulp reflux system is capable of reducing liquid pressure in the pulp refluxing pipe according to demands, so that damages to the pulp refluxing pump caused by pulp leakage are avoided so as to ensure normal production.

Description

technical field [0001] The invention belongs to the field of bean curd stick processing, and more specifically relates to a pulp return system for bean curd stick production. Background technique [0002] Tofu skin is also called oil skin, which is a layer of oil film on the top of soy milk after boiling. It is good for fresh food and can be stir-fried. After drying, it can be made into skin and silk. [0003] Tofu clothing is a traditional bean product of the Han nationality, and there are many famous dishes in the southern and northern regions of China. One is "picked" tofu skin, also called "oil skin", "yuba" and "tofu skin"; the other is pressed tofu skin, which is similar to tofu, but thinner (obviously thicker than oil skin), slightly Dry, sometimes with salt, the taste is different from tofu. Although both are called "tofu skin", they are quite different in shape, composition, taste and cooking methods. [0004] Tofu skin is one of the traditional specialties of my...

Problems solved by technology

Although both are called "tofu skin", they are quite different in shape, composition, taste and cooking methods.

[0009] However, in the process of follow-up use, the applicant found that no matter whether it is the salt water bean curd clothing automatic forming machine or the device for producing bean curd sticks, a slurry return system is provided, and a slurry pump is provided in the slurry return system. figure 1 As shown, when the liquid pressure is not enough, the soybean milk gathers at the slurry pump 3 from the slurry return pipeline 1, but it does not flow out from the slurry delivery pipeline 2 in time, and accumulates in the pipeline of the slurry return system, and will be pumped from the slurry Leakage at the pump 3 is likely to cause damage to the pump 3, not only need to replace the pump 3 to increase costs, but also cause economic losses due to production delays
