Juice pulp separation

Juice pulp separation is a key step in the juice production process. It involves separating the solid particles (such as pulp, pomace) in the juice from the liquid part to obtain clear juice. The following is a detailed introduction to juice pulp separation: 1. Purpose of separation The main purpose of juice pulp separation is to improve the transparency and taste of the juice, while removing unnecessary solid particles to ensure the quality and hygiene standards of the juice. In addition, the separated pomace can be further utilized as a by-product, such as making jam, feed, etc. 2. Separation methods 1. Mechanical separation method: - Centrifugal separation: Use a centrifuge to separate the solid particles and liquid in the juice. The centrifuge uses the centrifugal force generated by high-speed rotation to throw the solid particles to the container wall, thereby achieving separation. - Filter press separation: The juice pulp is passed through the filter medium (such as filter cloth, filter screen, etc.) by pressure, and the solid particles are trapped on the medium, while the clear juice flows out through the medium. 2. Physical separation method: - Sedimentation separation: Utilize the density difference between solid particles and liquid, let the solid particles naturally settle to the bottom under static conditions, and then take out the clear juice from the top. - Flotation separation: fine bubbles are introduced into the juice slurry, so that solid particles attach to the bubbles and float to the liquid surface, thereby achieving separation. 3. Bioenzyme separation method: - Use specific bioenzymes (such as pectinase) to decompose the pectin in the pulp, making the pulp loose and easy to separate mechanically. 3. Separation equipment - Centrifuge: used for high-speed centrifugal separation of solid particles in juice. - Filter press: used for pressing juice to separate solids and liquids. - Sedimentation tank: used for physical precipitation separation. - Enzyme treatment system: used for bioenzyme separation. 4. Separation effect The effect of juice slurry separation depends on the selected separation method and equipment. Ideally, the separation process should ensure that the clarity, taste and nutritional content of the juice are not affected, while maximizing the recovery of useful components in the pomace. 5. Environmental impact The pomace generated during the separation of juice slurry needs to be properly handled to reduce the impact on the environment. Usually, the pomace can be treated by composting, fermentation and other methods to achieve resource utilization. In short, juice slurry separation is a crucial step in juice production. Through reasonable separation technology and equipment, the quality of juice can be improved and the recycling of resources can be achieved.
