Vacuum Concentrating Pot

The Vacuum Concentration Pot can be also called a vacuum boiling tank, or vacuum cooking tank, it is a special evaporator that comprises an effective cooking and thickening process for the batch production of jams, marmalades, honey, corn syrup, compotes and jellies.

This cooking module is particularly suitable for small production amounts, for the development and optimization of production processes or as a pilot plant. Its various components are modular, and rack-mounted and enable simple transportation and short installation times.

The batch vacuum concentration tank is composed of the main body of the thickening tank, condenser, cooler, gas-liquid separator, vacuum pump, liquid receiving tank, valve pipeline, electrical control system, etc. The equipment is all made of stainless steel 304/316L, finely polished inside and outside, no dead corners, good corrosion resistance, a beautiful appearance, and unique structure.

A vacuum concentration pot is a type of food processing equipment used for the evaporation of liquids from food products, such as juices, sauces, and soups. The pot is designed to create a vacuum environment inside the chamber, which reduces the boiling point of the liquid being processed, allowing it to evaporate more easily and quickly.

The vacuum concentration pot consists of a cylindrical or spherical chamber made of stainless steel or other suitable materials. The chamber is mounted on a support structure and has a lid that can be sealed tightly to create a vacuum. The lid may be equipped with ports for monitoring the process, adding ingredients, or removing the product.

Inside the chamber, there is a heating element that heats the liquid being processed. The liquid is constantly stirred by an agitator to ensure even heating and prevent scorching. As the liquid boils, the vacuum environment reduces the boiling point, causing the liquid to evaporate more rapidly than in normal atmospheric conditions. The evaporated liquid is then condensed and collected for reuse or disposal.

Vacuum concentration pots may also have additional features such as a condenser to collect the evaporated liquid, temperature controls, and safety systems to prevent overpressure or overheating. They are typically used in food processing facilities for the production of concentrated products such as fruit juices, sauces, and soups, and can be used in conjunction with other equipment such as homogenizers and filling machines to create a complete production line.

The material liquid enters the vacuum concentration tank by the feed pump or through the vacuum self-priming method, and the temperature rises through heating by the heating medium (steam or heat transfer oil) in the jacket. Under the condition of vacuum negative pressure, the boiling point of the material liquid decreases, when it reaches a certain temperature, it starts to boil and evaporate. The generated water vapor is separated by the vapor-liquid separator and then enters the condenser. It is condensed into liquid under the action of the external circulating cooling water and sent to the collection tank. Part of the uncondensed water vapor will be discharged through the vacuum pump. As the water vapor is continuously evaporated, the concentration of the material liquid is getting higher and higher. When the concentration required by the process is reached, the material liquid can be discharged to obtain the final concentrated liquid.

1. It has a wide range of applications and can be used for the evaporation, concentration, crystallization or recovery of different materials and liquids in a variety of industries.
2. Evaporate under vacuum negative pressure, low evaporation temperature, suitable for heat-sensitive liquids.
3. The special stirring device is beneficial to speed up the evaporation rate, increase the concentration ratio, and is beneficial to the collection of paste or crystallization.
4. It is more suitable for pilot production or laboratory use in enterprises with small processing capacity.
5. It can be operated under negative pressure or atmospheric pressure, and can also be used for batch or continuous production.
6. It integrates multiple functions such as heating and boiling, stirring and liquid preparation, atmospheric evaporation, vacuum concentration, condensation recovery, etc., with strong versatility.
7. Made of high-quality stainless steel materials, clean and sanitary, no dead ends, and corrosion-resistant.
8. The vacuum pump and other parts are selected from high-quality brands to ensure the stability and reliability of the entire vacuum system.
9. The heating mode can be designed as steam heating or electric heating according to the user’s working conditions to meet the needs of users without a boiler heat source. The high-temperature insulation layer can effectively heat insulation, reduce energy consumption, and effectively avoid operator scalding accidents, operational safety.
10. With a batch pan evaporator, product residence time normally is many hours. Therefore, it is essential to boil at low temperatures and high vacuum when a heat-sensitive or Thermo degradable product is involved.
