Squeezing system and squeezing process for high-salt liquid sauce

Abstract

The invention provides a squeezing system and squeezing process for a high-salt liquid sauce, belonging to the field of squeezing of sauces. The squeezing system is characterized by comprising a sauce mash squeezing system, a pneumatic system and a water-circulating pipe system, wherein the sauce mash squeezing system is connected with a feed inlet of an isobaric tank through an underflow pump, a discharge outlet of the isobaric tank is connected with a feed inlet of a membrane plate-type filter press, discharge outlets of the membrane plate-type filter press are separately connected with a salt dissolving pond and an oil storage tank, the salt dissolving pond is connected with the oil storage tank through a material pump, an air compressor of the pneumatic system is connected with the air inlet of the isobaric tank, water storage tanks of the water-circulating pipe system are separately connected with a high-pressure pump and a low-pressure pump, the high-pressure pump is connected with a membrane plate water filling port of the membrane plate-type filter press, and the low-pressure pump is connected with the discharge outlet of the membrane plate-type filter press. The squeezing system provided by the invention needs low investment; the squeezing process is excellent; high production efficiency and high crude oil removal quality are obtained; and labor intensity of workers is low.

Description

technical field [0001] The invention belongs to the field of soy sauce pressing production, and in particular relates to a high-salt dilute soy sauce pressing system and a pressing process thereof. Background technique [0002] With the advent of the 21st century and the improvement of people's living standards, my country's condiment industry has developed rapidly, with a total output of more than 10 million tons, becoming a new economic growth point in the food industry. Relevant departments of the state pay more and more attention to the industry management of seasoning production and sales; the quality and standardization work is further strengthened; the pace of international integration is accelerated; the pattern of "small products, big markets" in the seasoning industry is taking shape; the development prospect is very broad. It is estimated that the revenue compound growth rate of the soy sauce industry in the next five years will be 16%, and the market size will in...

AI Technical Summary

Problems solved by technology

[0005] At present, the first crude oil pressing of domestic high-salt dilute soy sauce uses the above-mentioned iron cage press. Because of its heavy weight and cumbersomeness, this equipment occupies a large area, requires high investment, requires a lot of labor, and has high labor intensity and high efficiency. Low

[0006] Diaphragm plate-type plate-frame filter press is mature equipment, but due to the huge feed pressure required, even if a high-power thick slurry pump is used, the feed and storage space of the press cannot be filled to meet the requirements of the equipment. Feed demand, so the industry generally believes that it is not suitable for use in the field of soy sauce pressing

Moreover, the traditional pressing method generally adopts one-time pressing, and the juice yield is low; while the continuous pressing used in the industry refers to the purchase of more than two pressing equipment, which is pressed in series, and the production cost is high, which is not an ideal way of pressing soy sauce.
