Small-sized pasteuring and quality preserving device for raw milk

Abstract

The invention discloses a small-sized pasteuring and quality preserving device for raw milk, belonging to the sterilizing and quality preserving field of small-sized liquid milk products. The small-sized pasteuring and quality preserving device comprises a liquid pump (2) and a raw milk storage tank (1), a small-sized sterilizing device (3), a water-cooled heat exchanger (5), a dual-purpose heat exchanger (6) and a finished product storage tank (8), five tank-shaped equipment and multiple electromagnetic valves distributed among the tank-shaped equipment; all equipment are connected to the electromagnetic valves through pipelines; working state of the equipment is controlled by a control circuit. Through the device, each typical temperature point of milk products during a machining process can be achieved, thus, any quantity of the raw milk can be processed to needed milk products for people; sterilized milk has the advantages that: a pasteuring standard can be met without destroying the nutrient and the like.

Description

Technical field [0001] The small-scale raw milk pasteurization and quality-preservation device mainly involves the sterilization and quality-preservation of small liquid dairy products. Background technique [0002] At present, the raw milk used by most dairy processing plants in my country is distributed by large-scale cattle farms, but in most cases, the dairy farms do not immediately deliver the milk after squeezing the fresh milk, but first in the large-scale cattle farms. It is stored in the quality-guarantee device for a period of time, and after a certain amount is accumulated, it will be distributed in a unified manner. After the raw milk that has been stored for a period of time is delivered to the sterilized milk processing plant, it is stored and processed by the plant to become finished milk, and finally to the consumer, it takes a long time, generally 4 to 6 days Even longer, so theoretically it cannot be called fresh milk. The way most small milk bars get raw milk ...

AI Technical Summary

Problems solved by technology

Most of the small milk bars obtain raw milk by going to the cattle farm to get milk. In this way, the raw milk usually does not exceed 24 hours from the time it is squeezed out to the milk bar. The processing method generally adopts heat insulation direct type and heat ring pump heating. The heating time is generally 0.5 to 1 hour, which will destroy the nutrients in the raw milk, and the raw milk taken from the cattle farm must be processed at one time. Greatly reduces the quality of dairy products
