生鲜果蔬冷库

果蔬保鲜冷库利用水在固液相变时释放或吸收大量潜热的特点果蔬保鲜冷库以水为基质在冬季以冰的形态体现出来同时利用其冻结时释放的大潜热维持库内果蔬不受冻害夏季再以这些冰为冷源维持果蔬贮藏所必须的低温高湿条件

The fruit and vegetable fresh-keeping cold storage uses water to release or absorb a large amount of latent heat when it is solid-liquid phase. The fruit and vegetable fresh-keeping cold storage is represented by ice in the form of ice in the winter and uses the large latent heat released during freezing to keep the fruits and vegetables in the library from freezing damage. Use these ice as a source of cold to maintain the low temperature and high humidity conditions necessary for the storage of fruits and vegetables.

特点

不用制冷设备仅用几台风机投资小维护管理费用少与普通利用氯利昂或氨制冷的机械制冷库相节电90％以上且没有任何污染库内冷源来自冰水低温稳定温度高保鲜品质好保鲜期长

自动化程度高管理方便

适宜在年平均气温低于13C冬季最低气温在8C以下的地区建库气温越低效果越好

penance and management costsand of the No refrigeration equipment. Use only a few fan， small investment， less maint

use of Chlorine Leon or ammonia refrigeration mechanical refrigeration library phase the sing electricity was above 90％and no pollution.

The rolls cold source from the ice water stable at low temperaturehigh humidity，fresh keeping good quality，long freshness

Ahigh degree of automation， easy to manage.

Is suitable in the annual erage temperature is lower than 13＇C.Winter temperatures database construction， the temperature， the lower the better the results.

性能指标

不用任何机械制冷设备利用自然冷源在班季陈外气温高达40C以内冬季库外气温路至-18C左右的地方库内温度始终能保持在23C的低温状态

在年平均气温为2-13C的地区都可建成这种完全没有机械制冷的利用自然冷源的保鲜贮威库

库内温度周年可保持在果蔬保鲜需要的低温温度可在1-10C以内调节

库内相对湿度一直可保持在90％以上这对普通机械冷库来说几乎整不可能达到的

Without any mechanical refrigeration equipment, the natural cold source can be kept at a low temperature of 23C in the local temperature range of up to 40C outside the winter season.

In areas where the annual erage temperature is 2-13C, it is possible to build such a fresh-keeping warehouse that uses no natural mechanical refrigeration.

The temperature inside the library can be maintained at a low temperature required for fresh-keeping of fruits and vegetables. It can be adjusted within 1-10C.

The relative humidity in the library can be kept above 90%, which is almost impossible for ordinary mechanical cold storage.

适用范围

适用于我国北方等高寒地区的果蔬保鲜贮藏对内蒙古与黑龙江等寒冷地域该库也可用来贮藏鱼肉等动物食品

If can be applied for fruits and vegetables fresh-keeping in northern China and other apline areas，and even con be used stare fish meat and other animal food in Inner Mongolia， Heilongjiang and other cold areas

规模形式

贮藏库容量100-5000吨

贮藏品种苹果梨桃葡萄菜花青椒等各种瓜果蔬菜

建筑面积15010000平方米按贮藏里计算，1平方米建筑面积可贮藏果蔬0.7-10吨

建筑形式因为保鲜库要利用自然冷源所以要根据建库立地条件在气候较冷或有可利用山洞的地方能大大节约建库开支

管理人员因为没有复杂的制冷设备温度可自动调节贮藏果蔬100-5000吨的库只需28名管理人员

Storage, apple, pear, grape, cauliflower, green pepper, etc.

The building area is 15010,000 square meters, calculated according to the storage. The building area of 1 square meter can store 0.7-10 tons of fruits and vegetables.

Because the preservation form needs to use the natural cold source, it is necessary to greatly se the construction cost in the place where the climate is cold or there is a mountain ailable according to the conditions of the construction site.

Managers can automatically adjust the storage of fruits and vegetables by 100-5000 tons because there is no complicated refrigeration equipment temperature. only 28 managers
