It is suitable for such water treatment equipment as pure water, mineral water, and beverage process water. It is mainly composed of the following equipment: Pre-treatment System (multi-medium filter, active carbon filter, ion exchanger, Millipore filter), membrane separation System (Ultrafilter, nanometer filter, RO System), electrodialysis device, sterilization System (UV device, ozone device) and so on.
Blending system refers to the equipment combination that the various raw and auxiliary materials and process water are extracted or dissolved by various process units according to the pre-determined process parameters, and then mixed and fixed to obtain semi-finished products; its main modules include hot water unit, saccharose filter sterilizing unit, juice/tea powder reconstitution unit, auxiliary material dissolving unit, tea extracting and filtering unit, powdered milk reconstitution mixing unit, blending constant volume unit, CIP cleaning unit, pipe unit, electrical control and central control units.
The product quality of the blending system is mainly determined by the rigorous design, perfect automatic control system and considerable experience in engineering installation. With its engineering design and installation experience of more than 2,000 large-scale projects, Newamstar has a professional design team and engineering installation team to provide you with professional and high-quality services.
Tea extraction refers to the operation of extracting effective ingredients from tea leaves by soaking in hot water. The purpose of this operation is to efficiently extract the effective ingredients of the plants to maintain the unique color, aroma, and taste of the tea liquor as much as possible and prevent the excessive dissolution of non-effective ingredients in the precipitated liquid of beverage.
The method of fractional extraction will be adopted, in which the first extraction will be performed by low temperature to protect the aroma component of the original solution and to dissolve the small molecule heat sensitive component; the secondary extraction uses high temperature to extract the macromolecular effective taste components in tea. At the same time, however, non-polyphenolic macromolecule compounds also dissolve together, which may cause beverage turbidity and sedimentation, which can be solved by controlling extractive parameters.
After the extraction, the clarification of the tea juice is carried out to remove impurities, gums, and non-polyphenol macromolecular compounds in the tea juice, so as to avoid turbidity and sedimentation during the shelf life of the product. Clarification methods include low-temperature sedimentation (high-speed centrifuge) and membrane separation (ultrafiltration), or a combination of the two methods.
Sugar is one of the main components that make up a fruit juice beverage. The process that sucrose is dissolved in water to make a single syrup is called sugar dissolving operation.
Sugar dissolving system include the following units:
Sugar powder delivery, sugar powder dissolution, syrup sterilization, syrup filtration and cooling, syrup storage and other units. In special cases, the syrup needs to be degassed. A typical thermal melting process shall be done at 85°C for 10 min, and then gradual cooling process will be done to drop the temperature to the operating temperature (below 40°C).
For cloudy juice, it is necessary to break down the fibers and granules by high-pressure homogenization to distribute them evenly and finely so as to improve the physical properties and the mouthfeel of beverage products. A plunger pump is generally used as the homogenizer. The liquid product flows at a very high speed through the narrow gap between the valve seat and the valve core. Under the triple action of the shearing effect, the impact produced by high-velocity jetting, and the cavitation effect caused by the instantaneous pressure drop, the material can be ultra-finely pulverized to form a liquid-solid dispersion.
The homogenization pressure of the juice can be 25-40 MPa, matching the use of the homogenizer of the domestic first-class brand. Degassing is to avoid oxidation, but it will remove volatile aromas at the same time. The solution to this problem is to add an aroma recovery device. Therefore, the two operations of homogenization and degassing should be carried out after proper heating. They are often used in series with UHT, that is, after the UHT preheating section.
The blended material, prior to be filled, needs to be sterilized with the most common process, thermal sterilization. According to different product characteristics, the subsequent matching of the filling process and the shelf life, ultra-high temperature treated (UHT) can be selected, usually heating to 130 °C for more than a few seconds.
Heat exchanger may be in the form of a plate, a tube, a bellows, or the like. For products with pulp particles or high viscosity, tubular exchangers must be used to prevent clogging. At the same time, the tubular heat exchanger also has a more powerful pressure bearing capacity.
For cloudy beverage or milk based juice, we recommend tubular UHT; for a clear juice, plate UHT can be used.
CIP system is to automatically clean all surfaces that come in contact with the product. The objects to be cleaned include the inner walls of tank, pipe, hydraulic cylinder, and other liquid passages.
It is usually composed of cleaning liquid storage tanks, acid-base adding device, heater, cleaning pump, return pump, pipelines, steam valve group, etc.
According to the different cleaning objects, it can be divided into single-channel, double-channel, and multi-channel . For automatic CIP, the concentrated acid and alkali adding, metering and the temperature of the cleaning solution are all automatically controlled. The cleaning program is also performed automatically after the parameter setting.
The automatic COP/SOP system can perform foam cleaning and disinfectant spraying on the surface of equipment with detergents and disinfectants. This system is suitable for cleaning and disinfecting chemicals including alkaline foams, acid-based foams, disinfectant foams, and peroxyacids, and has been effectively used in food processing companies of beverages, beer, or milk.
Disinfectant blending system adopts the method of adding disinfectant original solution to the water to sterilize the inner and outer surfaces of the packaging materials used for the production line, such as bottles and caps.
Carbonating mixer is the equipment to mix sugar syrup, water and carbon dioxide. The product water is degassed and mixed with the syrup in a fixed proportion, cooled to the process temperature through a plate heat exchanger, and then fully mixed with carbon dioxide to complete carbonation.
