How to select equipment for a food factory? Master all the key points!

一、Selection principles

First of all, the equipment must meet the requirements for food safety and hygiene. Materials in contact with food should be made of stainless steel (such as 304 or 316L), food-grade plastics, etc., which are corrosion-resistant and easy to clean. The structure should avoid any hygiene dead corners and be easy to disassemble and clean.

Secondly, the equipment performance must meet the requirements of the process parameters, including processing capacity, temperature range, pressure level, operational accuracy, etc., and a certain margin should be reserved to accommodate fluctuations in production capacity.

Thirdly, priority should be given to the use of energy-saving and environmentally friendly equipment to reduce energy consumption of steam, electricity, water, etc., and to minimize wastewater and waste gas emissions.

二、Key steps in the selection process

Clarify the process requirements：Sort out the product types, raw material characteristics, production scale, and process flow. Determine the functions and specifications of the equipment required for each process.

Investigate the types of equipment：The same process may have multiple equipment forms. For example, drying can be done using belt drying, spray drying or vacuum drying. The most suitable type needs to be selected based on factors such as the thermal sensitivity of the material, moisture content, and particle requirements.

Examine the technical parameters：The key points for comparison include processing capabilities, power consumption, floor space dimensions, control methods, and maintenance convenience, among others.

Cost assessment and after-sales service：Calculate the total life cycle cost by considering the equipment price, installation fee, and operation and maintenance costs, and also assess the technical support and spare parts supply capabilities of the suppliers.

三、Typical Precautions

• The conveying equipment should minimize the residue of materials and prevent cross-contamination.

• The heat exchange equipment gives priority to structures that have efficient heat transfer and are easy to clean.

• Equip explosion-proof and dust-removal devices for processes involving dust.

• The interface dimensions of the equipment and the control system should be compatible with the pipelines and automatic control system of the entire plant.

In conclusion, the selection of food equipment should be based on actual production conditions, balancing technological advancement and economic rationality. Priority should be given to ensuring food safety and stable operation, laying the foundation for long-term and efficient production.
