Description
Technical field
The utility model relates to the freezer preservation, and is especially a kind of for the preservation Chinese chestnut, keeps the Chinese chestnut freshness, the Chinese chestnut preservation freezer that preservation is effective.
Background technology
Chinese chestnut is a kind of good woody grain and commerical tree species, strong stress resistance, and wide adaptability has the advantages such as the easy grasp of cultivation technique, and 1 year kind is received for many years, and output is more stable, and income is large.Generally gather take off bud after, deposit at normal temperatures about a week, loss reaches 30%, even up to more than 50%, except the weather reason, also because chestnut fruit water content is high, reaches 40 ~ 60%, respiration is strong, very easily dehydration is air-dry.Carbohydrate containing contains 40 ~ 45% in addition, and major part is starch, and enzymes activity is strong, and Starch Hydrolysis is fast, discharges a large amount of respiration heats, and is too high if pile up this moment, and ventilation heat radiation is bad, easily produces anaerobic respiration and causes rotten going rotten.Sometimes also can germinate in storage and shorten freshness date, causing the loss of its nutritive value and economic worth.
In the suitability for industrialized production of Chinese chestnut, for the seasonal that satisfies large-scale need of production and overcome Chinese chestnut, so manufacturer all adopts the mode of freezer preservation to realize the fresh-keeping of Chinese chestnut.
General freezer freezes with mechanical means, and the most mechanical freezers of China are mainly to adopt steam compression type refrigeration mode regulation warehouse temperature at present.Refrigeration principle is the evaporation that utilizes the lower liquid refrigerant of vapourizing temperature, absorbs the heat in storage environment, thereby the storehouse temperature is descended.Cold-producing medium after vaporizing by compressor sucks back and pressurizes, and cold-producing medium passes to cooling medium with the heat that absorbs in condenser, makes self temperature be minimized, be condensed into liquid, and then carries out evaporation endothermic, and so circulation can realize continuous cooling.
General freezer is many by the refrigeration machine refrigeration, utilizes the very low liquid of gasification temperature (ammonia or fluorine Lyons) as cooling agent, and it is evaporated under the condition that low pressure and machinery are controlled, and absorbs the heat in storage, thereby reaches the purpose that cools.The most frequently used is the compression reezer system, mainly is comprised of compressor, condenser, choke valve and evaporation tube etc.Can divide again directly cooling and indirect cooling two kinds according to the mode of evaporation tube device.Directly cooling evaporation tube is arranged in the refrigeration storehouse, liquid coolant is during through choke valve, directly absorbs the heat in storehouse and lowers the temperature.Indirectly cooling is by air blast, the air in storehouse to be aspirated into air-cooling apparatus, after air is hovered above evaporation tube heat absorption in cooling device, then sends into Ku Nei and lowers the temperature.
Realize the cold storing and fresh-keeping effect of Chinese chestnut, need strict control to temperature, the humidity of preservation process.Because excess Temperature can cause and go mouldy, too low can the causing of temperature damaged to plants caused by sudden drop in temperature, and humidity is apt to deteriorate too greatly, and humidity is too little can become dry, and loses its local flavor, and will prevent Chinese chestnut from producing anaerobic respiration and cause rotten going rotten.
Guarantee the fresh-keeping effect of Chinese chestnut, the time of its temperature being down to as early as possible 0 ~-2 ℃ is extremely important, and the time that reaches is longer, and the probability that Chinese chestnut goes bad is larger, and the loss large percentage is therefore cooling with Chinese chestnut as early as possible.Same cooling 10t Chinese chestnut is only adopted the directly mode of refrigeration, and Chinese chestnut is cooled to 0 ~-2 ℃ needs the time of 12h, and adopts indirectly mode, needs the time of 6h.
Existing freezer is all that employing is directly cooling or indirectly cooling separately, and cool time is longer, and when a large amount of Chinese chestnut of needs storage, required cool time is longer, and is unfavorable for the fresh-keeping effect that keeps Chinese chestnut.
Simultaneously, because the respiration of Chinese chestnut is more vigorous, various physiology processes are carried out sooner, and the life-span of the rear storage of gathering is just shorter.The breathing of Chinese chestnut is divided into two kinds of aerobic respiration and anaerobic respirations, and aerobic respiration is to absorb oxygen from air, and sugar, organic acid, starch and other substance oxidation are decomposed into carbon dioxide and water, emits simultaneously a large amount of heat, causes Chinese chestnut heating mildew; And the energy Ratios aerobic respiration that anaerobic respiration discharges is few, but can produce a large amount of ethanol, acetaldehyde and other harmful substance in the anaerobic respiration process, and these harmful substances can accumulate in cell, and transporting makes the Chinese chestnut cytotoxic in other tissue.Therefore, should manage to suppress to breathe in storage, can not too suppress again, and existing freezer only arranges Yishanmen usually for turnover, a large amount of Chinese chestnuts are after storage a period of time, because ventilation has some setbacks, after the interior oxygen expenditure of freezer is complete, Chinese chestnut will enter anaerobic respiration and produce a large amount of harmful substances, affect the Chinese chestnut quality.
Because traditional freezer refrigerating speed is slow, its inner air circulation is poor, causes fresh Chinese chestnut usually can only preserve maximum 8 months, is not suitable for long preservation.
Summary of the invention
To be solved in the utility model is exactly that the independent employing of existing freezer is directly cooling or indirectly cooling, and cooling velocity is slow, and the problem of inapplicable a large amount of Chinese chestnut preservations provides a kind of cooling velocity fast, effective, can keep the Chinese chestnut preservation freezer of Chinese chestnut freshness.
Chinese chestnut preservation freezer of the present utility model, comprise storehouse and compressor, it is characterized in that this freezer also is provided with air-cooler and comb, air-cooler all is connected with compressor with comb, comb is arranged on storehouse top, air-cooler is three groups, is arranged on comb top, and three groups air-coolers are equidistant to be arranged on a side walls of storehouse.
Described every group of air-cooler is provided with three fans, accelerates flowing of cold air.
Described storehouse is provided with two inlet/outlets, and two inlet/outlets are separately positioned on wall relative before and after storehouse, after two fan inlet/outlets are all opened, can accelerate Air Flow in storehouse, and the reducing air in storehouse is discharged as early as possible.
Go back set temperature detector and humidity measurement instrument in described freezer, for detection of with the temperature and humidity of controlling in freezer.
Described storehouse adopts the thick polyurethane double-side color steel wall plate of 15cm to be welded.
When the needs fast-refrigerating, simultaneously open cold blower fan and comb, temperature by comb fast reducing comb surrounding air, utilize simultaneously the fan of air-cooler the cold air around comb to be blown to fast the Chinese chestnut place of storehouse below, the temperature of fast reducing Chinese chestnut is still pressed the 10t Chinese chestnut and is calculated, and can temperature be reduced to 0 ~-2 ℃ in 1 ~ 2 hour, guarantee quality and the freshness of Chinese chestnut, avoid Chinese chestnut rotten; After temperature is down to 0 ~-2 ℃, close air-cooler, only need use comb automatically to control in freezer temperature and remain between 0 ~-2 ℃ and get final product, effectively energy savings, can also avoid air-cooler that Chinese chestnut is dried up; In preserving process, opened the inlet/outlet before and after freezer in every 5 ~ 7 days one time, while open cold blower fan, utilize the off-air in air-cooler quick-replaceable freezer, replenish fresh air, in order to keep the aerobic respiration of Chinese chestnut, stop to cause Chinese chestnut to enter anaerobic respiration because lacking oxygen, and producing a large amount of harmful substances, time of exchanging gas is about 2 hours.
