Concentration device for high-concentration and high-viscosity liquid

Abstract

The invention discloses a concentration device for a high-concentration and high-viscosity liquid. The concentration device mainly comprises a liquid storage tank, an osmosis device, an extracting solution storage tank and a circulating pump. According to the concentration device, a forward osmosis membrane is adopted as the osmosis device and matches an extracting solution, osmotic pressure difference is generated on the two sides of the forward osmosis membrane, heating and mechanical external pressure applying are not needed when high-concentration and high-viscosity liquid is concentrated, loss of nutritional ingredients is reduced, energy is saved, and the production cost is reduced; the osmosis device is arranged in the liquid storage tank, the surface of the osmosis membrane element can be kept clean for a long time, the service life is prolonged, and cleaning and maintenance are convenient; and the extracting solution can be replaced under the condition of not influencing the normal operation of the device, so that the long-period operation of the device is ensured.

Description

technical field [0001] The invention belongs to the technical field of liquid concentration, and in particular relates to a high-concentration and high-viscosity liquid concentration device. Background technique [0002] Fruit juice is an important branch of my country's beverage category, which can be divided into low-concentration fruit juice, medium-concentration fruit juice and pure fruit juice. Juice is a juice product obtained from fruit as raw material through physical methods such as pressing, centrifugation, extraction, etc. Since concentrated juice can greatly reduce packaging, transportation and storage costs, a large amount of concentrated juice will be used in the entire juice market. [0003] The main juice concentration methods currently used are multi-stage flash heating, membrane distillation and other methods. The commonality is that the raw materials need to be heated to different degrees, so the traditional juice concentration method will have a great im...

Problems solved by technology

The commonality is that the raw materials need to be heated to different degrees, so the traditional juice concentration method will have a great impact on the quality of the juice, such as loss of sugar, vitamins, polyphenols and other nutrients, and even change the color of the juice itself and taste, resulting in a decline in consumer taste and perception quality

[0004] In addition, some liquids with high concentration, such as fruit juice, jam, essence, spices, traditional Chinese medicine, etc., have high viscosity and solid content. Using conventional heating and concentration devices, the liquid is easy to adhere to the heater, reducing the heat transfer efficiency. Even damage the heater, resulting in higher disposal costs

[0005] Therefore, how to minimize the loss of active ingredients in the liquid concentration process to ensure the quality of the concentrate, and how to solve the problems of short processing cycle and high cost in traditional heating and concentration, are the current key research directions in the field of liquid concentration.
