Fine Design of Slaughtering and Processing Cold Storage

Have you encountered these situations in the design, installation and use of slaughtering and processing cold storages:

• High operating cost of slaughtering and processing cold roomSerious weight loss of meat during storage in cold room
• Wear and tear of equipment accelerates in high humidity environment
• Ice blockage in refrigeration equipment

During the process of designing the slaughtering and processing cold room, it is important to thoroughly considering the actual environment of each slaughtering step and the differences in its demand. Besides integrating functionality and practicality into the design, paying attention to every design detail is also the key to success. In this Solution, Eden's engineers have reduced the energy consumption and operating costs by replacing the traditional design of single refrigeration system with heat recovery system and hot gas bypass. Moreover, the adverse effects of high humidity environment on equipment operation and maintenance are reduced by using Eden’s customised unit coolers. Due to its high cooling efficiency and uniform and gentle air flow, the moisture and the nutrients of ingredients can be adequately retained, Therefore, the weight and nutrition of meat will not be lost during storage.

| Slaughtering and Processing Cold Room Project

The slaughtering and processing factory covers an area of about 11,000 m² with three areas, i.e., slaughtering area, by-product processing area and finished product processing area. It plans to slaughter 3,000 sheep daily.

Energy Saving & Consumption Reduction - Benefiting from the Heat Recovery System and Eden Hot Gas Bypass Technology

The hot gas discharged from the compressor enters the Eden unit cooler via an oil separator that separates the oil from the hot gas. It melts the frost formed on the external surface of the cooler, therefore eliminating the additional energy consumption required by traditional electric defrosting. In this project, all the freezing room, cold room and cooling room adopt Eden unit coolers with hot gas bypass technology, helping slaughtering and processing cold room to reduce its energy consumption and emissions while achieving high-efficiency defrosting. Moreover, the heat recovery system is applied to the floor insulation, using glycol as the ground insulating medium to protect floor heating treatment done in the cold area. The system can recover the heat in the high-temperature and high-pressure refrigerant discharged from the compressor, thereby improving the energy efficiency and optimizing the operational energy efficiency of the entire refrigeration system.

Suitable for High Humidity Environment — Eden Customised Unit Coolers

When the carcass is deposited in the freezing room with high humidity, the water vapour in the air will attach to the fins of the cooler and condense into frost or create an ice blockage. The frost on the fins will easily block the air way, which makes the temperature of the cold room unable to reach the expected standard. In addition, the compressor efficiency will be lowered, increasing the energy consumption of the refrigeration system. For this specific storage environment, Eden customised unit coolers are designed with a large fin spacing, effectively solving the hidden problem of frost blockage, reducing energy consumption and being more energy efficient. The stainless steel casing of the cooler has good impact and corrosion resistance, maintaining excellent durability in high-humidity environments.
