Tube-type UHT high heat recovery rate hot water heat exchange system

Abstract

The invention relates to a tube-type UHT high heat recovery rate hot water heat exchange system. In a product pipe, a balance tank, a product pump, a degassing section, a heating section, a sterilization section, a heat recovery section, a tower water cooling section and an ice water cooling section are orderly arranged in the product pipe from an inlet to an outlet. A hot water pipe comprises a heat recovery section hot water circulation part and a sterilization hot water circulation part. The heat recovery section hot water circulation part orderly comprises a cooling hot water tank and a cooling hot water pump and the hot water orderly flows through a heat recovery section, a heating section and a degassing section and finally returns to the cooling hot water tank. The sterilization hot water circulation part orderly comprises a sterilization hot water tank, a sterilization hot water pump and a steam section and the hot water flows through the sterilization section and finally returns back to the sterilization hot water tank. Through a reasonable flow ratio of hot water to product, a high heat recovery rate is obtained.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of beverage production, in particular to a tubular UHT hot water heat exchange system with high heat recovery rate. [0003] 【Background technique】 [0004] The current hot water heat exchange system of tubular UHT, such as figure 2 As shown, the product pipeline includes a balance tank 1, a product pump 2, a degassing section 3, a sterilization section 5, a heat recovery section 6, a tower water cooling section 7, and an ice water cooling section 8 in sequence from the inlet to the outlet; hot water The pipeline includes a hot water tank 9, a hot water pump 10, flows through the heat recovery section 6, a steam section 13, flows through the sterilization section 5, flows through the degassing section 3, and finally returns to the hot water tank 9. The hot water heated by steam is used to heat and sterilize the product, and then cooled to the filling temperature. In order to save the consumption of...

Problems solved by technology

The heat recovery rate of this method is not high. If the heat recovery rate is to be increased, the heat exchange area required by the sterilization section 5 will increase, which will increase the high temperature time of the product in the sterilization section 5, which is not conducive to maintaining the flavor of the product.
