在大型食品加工中心中，通常会设计很多温度带，并且这些温度带散布在厂区的各个角落。

In large food processing centers, many temperature zones are usually designed, and these temperatures are scattered around the factory floor.

食品冷库在某项目设计中，园区总建设面积30000㎡，其中建设有快速冷却间、快速冻结间、制冰间、储冰间、加工操作车间、低温穿堂、高低温冷藏库数十间，分布于不同的楼层，和不同的生产车间。

Food storage in a project design in the park, a total construction area of 30000 square meters, of which construction of rapid cooling, quick freezing, ice making, ice storage, processing workshop, low-temperature Chuantang, high and low temperature cold storage among dozens, distributed in different floors, and different production workshop.

如何科学的配置制冷系统成为了关键课题。经过反复的测算和研讨，最终决定：快速冷却间和快速冻结间由于温度波动大，进出货物时间不固定，采用独立系统控制。

How to scientifically configure the refrigeration system has become a key issue. After repeated calculations and discussions, the final decision is made: the rapid cooling room and the rapid freezing room, due to temperature fluctuations, the goods out of time is not fixed, the use of independent system control.

其余车间采用，桶泵强制供液系统，分别作为低温、高温区域的供液系统。并且系统间安装了过桥阀，可以相互借冷，满足货物吞吐量突然增加或者系统故障是的使用需求。

The other workshops use bucket pump forced liquid supply system, respectively as low temperature and high temperature supply system. And the system installed a bridge valve, you can borrow each other cold, to meet the sudden increase in cargo throughput or system failure is the use of demand.

在快速冷却过程中，还有一个十分重要的因素——风速，而这个因素也往往是被人们所忽视的。

In the rapid cooling process, there is a very important factor wind speed, and this factor is often overlooked.

而在快速降温的过程中，往往需要较大的空气流速和较大的换热温差来满足换热需求，但是许多食品在大风速和大温差的作用下，表面会萎缩，甚至变形，严重影响产品的商品价值。

In the process of rapid cooling, often require larger air velocity and large temperature difference of heat exchanger to meet the heat demand, but a lot of food in high wind speed and large temperature difference under the effect of surface will shrink, and even deformation, seriously affect the product value of the goods.

在这类产品的冷却过程中，通常不能用冷风直吹产品表面，而是应该采用回风冷却的形式，温差也不宜过大，尽量控制在5~10℃左右(部分产品存在差异)，避免表面快速冷却产生的形变。

In the cooling process of this type of products, products are usually not blowing straight surface with cold, but should be used in the form of air cooling, the temperature difference is not too large, as far as possible at 5~10 Deg. C (some products differences), avoid deformation of rapid cooling of the surface is generated.
