Project Description

Enzymatic Hydrolysis Tank


This series of enzymatic hydrolysis tanks is a fully enclosed, vertical structure sanitary and clean enzymatic hydrolysis reaction equipment. It has been widely used in enzymatic hydrolysis technology in food, beverage, biological engineering, Enzymes are used as catalysts for substances in the pharmaceutical and other industries, and full enzymatic hydrolysis reactions are carried out with the help of the operation of the agitator under suitable temperature and pH conditions.

Enzymatic hydrolysis tank is specially used for fruit and vegetable juice, animal and plant and other substances. Enzymes are used as catalysts for decomposition reaction. The materials in the tank decompose various organic polymers under suitable temperature and pH conditions by the operation of agitator to make them organic Small molecules facilitate the assimilation of the body.

The enzymolysis tank is triple layers, which have the functions of heating, insulation, heat preservation and stirring. After the enzymolysis is completed, steam can be introduced into the enzymolysis tank jacket to raise the temperature of the material to 80-100℃ to inactivate the enzyme. After the enzyme has been inactivated, the material can be cooling down certain temperature through cooling water medium. The temperature of the materials in the enzymolysis tank is around 50℃ during enzymolysis, and the enzyme inactivation temperature is 90℃. Therefore, users need to prepare their own heat medium. The common heat medium is steam or hot water.

Fruit juice contains substances such as protein and starch, which are easy to denature and difficult to preserve. These substances must be enzymatically hydrolyzed during the production process. Generally, pectinase, amylase, 43# enzyme is added to decompose the protein and starch in the juice. Molecular compound. The juice feed generally enters from the bottom of the tank. When the juice reaches the agitator shaft, the agitator is turned on. When the tank is full, the agitator stops and the enzyme is added from the top of the tank.

The enzyme is kept at 50-53°C in the tank and allowed to stand for 90 minutes until the decomposition is basically completed. After the enzymolysis, add gelatin, stir for 5 minutes, turn off the stirring, let it stand for 35 minutes, and then discharge. The total working time of the enzymolysis process is 130-150min, so in order to ensure continuous production, the enzymolysis tank is generally equipped with 3-4 sets.

For different materials, choose a suitable and effective mixing device to achieve the purpose of full mixing and efficient mixing. Before quotation, users need to provide material name, material characteristics (PH value, viscosity value, etc.), enzymatic hydrolysis process, tank volume and so on.

Enzymatic hydrolysis tank


  1. Enzymolysis tank can be equipped with quick-opening sanitary manhole, sight glass, thermometer, respirator, CIP cleaning ball, material inlet and outlet, sampling port, PH meter port, SIP sterilization port, anti-vortex plate, liquid level indicator, hot and cold medium inlet and outlet, agitatior device, etc.
  2. The surface of the inner tank body is mirror polished, and the openings of the inlet and outlet pipes, sight glasses, manholes and the welding place of the inner tank body are all used in the arc transition of the inner tank body, smooth and easy to clean, no dead corners, and the production process is hygienic and stable.
  3. The outer surface of the tank is mirror-polished with stainless steel plate, and the primary color is matt or frosted, and the appearance is beautiful and clean.
  4. An insulation layer is set between the jacket and the outer cylinder, and the inside is filled with high temperature resistant, anti-aging rock wool or pearl wool for heat preservation, which not only heats insulation, but also prevents the operator from scalding.
  5. The tank material can be made into SUS304 or SUS316L according to customer requirements.
  6. The top of the tank is equipped with a paddle-type agitator to make the material stored in the tank more fully agitated. The mixing motor is controlled by frequency conversion, which makes the service life of the motor longer. A thermometer and a washer are installed on the cylinder to facilitate the measurement of the temperature of the liquid material in the tank and the cleaning of the tank liner.

Use and Maintenance

Before using the batching tank, the inside of the tank must be cleaned with light hot water, and then sterilized with steam. Various materials enter the tank through the material pipe fixed on the tank lid, or open the hand hole to pour in. The input material should not be filled too full.

After the ingredients are finished, drain the remaining materials in the tank, rinse with warm water as soon as possible, brush off the attached materials, and then use 75℃-85℃ alkaline water to clean the inner wall of the container. And rinse with clean water, to be used next time.

Always pay attention to the working conditions of the entire equipment and reducer. If the lubricating oil of the reducer is insufficient, it should be refilled and replaced every six months (40# engine oil). When the equipment is not in use, be sure to clean the inside and outside with warm water instead of saltwater. Rinse to avoid corrosion, often scrub the cylinder body to keep the exterior clean and the inner tank bright, so as to achieve the purpose of durability.
