Applications in the Food and Beverage Industry

Beverage production typically comprises four core stages—ingredient preparation, mixing, sterilization (UHT/pasteurization), and filling—with sanitary fluid handling equipment utilized throughout the entire process.

Brewing is a prime example of batch production, characterized by distinct stages such as mashing, fermentation, maturation, and filtration; consequently, the equipment requires flexible flow paths and must be easy to disassemble and clean.

Condiments encompass soy sauce, vinegar, sauces, mayonnaise, and ketchup, among others; the products span a wide range of viscosities—from low-viscosity soy sauce to high-viscosity mayonnaise and ketchup—and some contain particulates or fibers.

The food and beverage industry is the sector where hygienic fluid equipment finds its most widespread application

Its scope extends far beyond dairy products, encompassing the processing stages of virtually all liquid foods—from beverages and brewing to condiments, edible oils, and central kitchens.

Key equipment and process steps

Sterilization: Fruit juices, tea beverages, and plant-based protein drinks typically undergo UHT (Ultra-High Temperature) sterilization or pasteurization. The equipment must withstand repeated heating and cooling cycles while ensuring that heat-sensitive components—such as vitamins and flavor compounds—are not excessively degraded.

Ingredient Preparation and Standardization:Ingredient/Mixing Tanks-Used for dissolving and mixing cream, skimmed milk, sugar, stabilizers, and flavorings.Buffer/Balance Tanks-Used for temporary storage prior to pasteurization, UHT treatment, or filling to ensure continuous production.Standardization Tanks-Used for adjusting fat content; equipped with agitation and ports for in-line monitoring.

Fermentation and Curding:Yogurt fermentation tanks-Feature jackets or coils, gentle agitation, CIP/SIP capabilities, aseptic vents, and uniform temperature distribution.Cheese vats/curd tanks-Used for curd formation, cutting, and whey drainage; typically equipped with cutting tools and drainage mechanisms.Whey storage tanks-For storing cheese by-products; sanitary-grade and corrosion-resistant.Lactose crystallization tanks-Used for lactose crystallization during whey processing; equipped with agitation and temperature control systems.
