The food industry plays a vital role in the world market. This large sector produces various products using different methods such as distillation, drying, and disinfection. The operations need to be considered and designed in a clean and hygienic environment. Most production of food factories works 24 hours per day with no stopping hour, which requires the high performance of instruments and high efficiency of machine support to produce stable steam with constant temperature and pressure.
How are boilers used in Food Industry ?
Within large areas of the food industry, the use of steam can be broken down into numerous processes such as:
Meat product: Steam for mashing, lautering, pressure cooking, roasting and hot smoking. Hot water for boiling, braising, cooking and steaming. Hot oil for frying.
Dairy product: Steam for pasteurizing, whey production, high-temperature processes, sterilizing, thermalization, and drying dairy powder.
Cooking oils product: Steam for drying and hardening. Hot water for deodorizing, bleaching, de-gumming, steaming and pressing/extraction.
Canned product: Steam for pasteurization and sterilization cans, containers and glass containers. Hot water for boiling and cooking processes.
Sugar and starch product: Steam for extraction, heating, evaporation, and crystallization, usually in conjunction with the CHP system (combined heat and power).
Confectionery product: Steam for dehydration processes such as freeze-drying and spray drying. Steam for oven baking processes such as roasting, tempering and conching. Steam for processing of sugar mass.
Snack food Product, Pet food product: Steam for sterilizing, preserving, extrusion and drying. Hot water for boiling and cooking processes.
CIP systems : The factories also need steam to apply with CIP systems (Clean in place) and cleaning processes.
