Spherical paste concentration equipment

The spherical paste concentration equipment mainly consists of four parts: the main body of the concentration tank, the condenser, the gas-liquid separator, and the liquid receiving bucket. It can be used for the concentration, distillation, and recovery of organic solvents in industries such as pharmaceuticals, food, and chemicals. Due to the use of vacuum concentration, the concentration time is short and it will not damage the effective components of thermosensitive materials. The parts of this equipment that come into contact with materials are made of stainless steel, which has good corrosion resistance, durability, and meets GMP standards.

It can be used in industries such as pharmaceuticals, food, and chemicals for the concentration, distillation, and recovery of organic solvents from feed liquids.

　　Spherical paste concentration equipmentIt refers to the process of evaporating a portion of the moisture in the liquid material to achieve the required concentration. There are generally two types of concentration methods, one is heating evaporation, including vacuum concentration and atmospheric pressure concentration; Another type is non heating evaporation, which includes freeze concentration and membrane technology concentration. Today, we will introduce one of them - vacuum concentration, and explain its purpose, advantages and disadvantages, principle characteristics, and classification.

1、 The purpose of vacuum concentration

1. Remove most of the moisture from food ingredients to reduce packaging, storage, and transportation costs.

2. By increasing the concentration of the product, the aim is to enhance its storage capacity.

3. Meet the process requirements of food processing, such as pre-treatment for product drying, dehydration, or crystallization.

During the concentration process, aromatic substances in the juice can be extracted.

2、 Advantages and disadvantages of vacuum concentration

1. Advantages

(1) Reduce boiling point, increase the temperature difference between steam and material, improve concentration rate, and minimize heat loss.

(2) Concentrate at low temperatures, suitable for food with low temperature characteristics, to prevent loss of thermosensitive substances.

(3) Low temperature steam can be utilized.

(4) It has a reverse osmosis effect, further improving the evaporation rate.

(5) Has a certain bactericidal effect.

2. Disadvantages

(1) The equipment requirements are numerous and high.

(2) High latent heat of evaporation (the lower the boiling point, the greater the latent heat of evaporation) requires a large amount of heat to evaporate.

3、 The principle and characteristics of vacuum concentration

1. Principle

The solution is heated, and the solvent molecules gain kinetic energy to overcome the intermolecular attraction and escape from the liquid surface. The steam molecules continuously supply thermal energy to the steam, which is constantly eliminated. In engineering, in order to improve this gasification speed, most gasification processes are carried out in boiling state.

2. Characteristics

(1) Most food ingredients with complex compositions have thermal sensitivity and quality requirements for product color, aroma, and taste, making the concentration of food strive for "low temperature and short time". Due to the boiling point of the liquid being related to external pressure, low pressure corresponds to low temperature, and vacuum concentration ensures the quality of the product.

(2) Vacuum concentration eliminates air and oxygen dissolved in the liquid, and due to the lack of oxygen in the evaporation space, it is beneficial for the processing quality of easily oxidizable materials.

(3) The evaporation rate is fast, saving time compared to atmospheric concentration.

(4) Plays a role in pre sterilization or partial sterilization.

(5) The enclosed operating space helps to reduce microbial contamination of materials.

4、 Classification of vacuum concentration equipment

1. Classified by the number of times the heating steam is utilized

Single effect concentration equipment, multi effect concentration equipment, and concentration equipment with heat pumps.

2. Divided by the process of material liquid

Loop, single program.
