Continuous extract thickening machine and work method and cleaning method thereof

Abstract

The invention provides a continuous extract thickening machine, which comprises a jacket heater. A feed pump is connected to the inlet of the jacket heater. The outlet of the jacket heater is connected to a heating chamber. The heating chamber is connected to an evaporating chamber. The evaporating chamber is arranged above a product receiving tank. A buffer tank is provided with an upper opening, a middle opening and a bottom opening. The upper opening of the buffer tank is connected to the inlet of a vacuum pump. The outlet of the vacuum pump is connected to a vacuum buffer tank. The middle opening of the buffer tank is connected to the lower opening of a condenser. The upper opening of the condenser is connected to a steam-liquid separator. The steam-liquid separator is connected to the upper opening of the evaporating chamber. The bottom opening of the buffer tank is connected to a vortex pump. The invention also provides a work method and a cleaning method of the continuous extract thickening machine. The continuous extract thickening machine can improve the product density and shorten the concentration time, at the same time, the energy consumption is little, and the cost is low. Furthermore, the continuous extract thickening machine can carry out concentration continuously, the work efficiency is largely improved, automatic online cleaning can be performed automatically, no dead angle exists in the machine, and the products will not be polluted by different products.

Description

technical field [0001] The invention relates to a concentrating device, in particular to a continuous extract thickening machine used for the concentrated production of plant extracts and food and beverages. Background technique [0002] In the current concentrated production of plant extracts and food and beverages, some products are required to be concentrated to 1:1.4~1:1.8 (paste), and due to the characteristics of the active ingredients of the product, long-term heating at high temperature will lead to loss of active ingredients or Completely ineffective. [0003] Traditional enrichment equipment has the following defects: [0004] 1. The product can only be concentrated to about 1:1.2 to 1:1.4; [0005] 2. The concentration process takes a long time, and the product is heated at high temperature for a long time. The contact between the product and the wall surface of the equipment is easy to gelatinize and coke, and the foaming material is often not completely concen...

AI Technical Summary

Problems solved by technology

[0004] 1. The product can only be concentrated to about 1:1.2 to 1:1.4;

[0005] 2. The concentration process takes a long time, and the product is heated at high temperature for a long time. The contact between the product and the wall surface of the equipment is easy to gelatinize and coke, and the foaming material is often unable to be completely concentrated, or the material is seriously lost during the concentration process, resulting in product loss.

[0006] 3. The concentration process consumes a lot of energy and costs a lot
