Abstract
The utility model relates to a device for precooling fruits and vegetables by the differential pressure, which relates to a preserving processing device after the fruits and vegetables are picked. The utility model is mainly composed of a blower fan and a static pressure box, wherein, the front surface of the static pressure box is provided with an air inlet corresponding to a basket stack channel only; the upper end of the blower fan is connected with a divergent air outlet. The utility model is characterized in that the basket stacks can be cooled uniformly and rapidly with good preserving effect, and compared with the prior art, the cooling time is reduced. The cooling time difference of fruit and vegetable baskets is less than half an hour. Therefore, the utility model has the advantages of low energy consumption and low running cost. On the other hand, since the volume of the static pressure box is small, the device space is effectively saved and the precooling capacity of the fruits and vegetables is enlarged.
Description
The utility model relates to the fresh-keeping treatment device after a kind of gourd, fruit and vegetable is adopted.
At present, along with the big circulation of vegetables and the prolongation of transportation range and improving constantly of living standards of the people, also just more and more higher to the requirement of quality of vegetable, especially the requirement to its quality, freshness and nutritive value increases day by day.And the present most of vegetables of China lose serious in storage, transportation and sales process owing to do not carry out effective post-harvest fresh-keeping processing.Cause enormous economic loss on the one hand, quality of vegetable is difficult to guarantee on the other hand.A lot of local, especially based on the rural area, employing be still the most original store method.And vegetables are adopted the back, transportation and before sales carry out precooling and can address the above problem effectively.Therefore, the vegetable precooling technology more and more is subject to people's attention, and its application is also more and more general.Some vegetables producers of China generally adopt freezer as precooling at present, promptly directly the vegetables after adopting are placed the intensive stacking of freezer, and it is lowered the temperature naturally.This kind method temperature fall time is long, needs 1-2 days approximately, and fresh-keeping effect is relatively poor.What generally adopt abroad is a kind of differential pressure precooling device, as support by Tokyo Co., Ltd. that virtuous hall nineteen eighty-three publishes about disclosed a kind of differential pressure precooling device in " maintenance of edible wild herbs freshness " book, it can shorten to pre-cool time 4-7 hour, has improved pre-cold efficiency effectively.But because this device structure design is reasonable inadequately, cause inhomogeneous and unnecessary vertically the leaking out of the horizontal air quantity of each dish basket, make it in temperature-fall period, the cooling of vegetables buttress each several part is inhomogeneous, has influenced fresh-keeping effect; Also exist the plenum chamber volume bigger than normal simultaneously, energy consumption is big, defectives such as operating cost height.
The purpose of this utility model and task are at the deficiencies in the prior art and defective, adopt the back precooling freshness retaining for vegetables a kind of new vegetables differential pressure precooling device is provided, this device not only can make the even fast cooling of basket buttress each several part, good refreshing effect, but also it is little to have an energy consumption, characteristics such as operating cost is lower, and floor space is little.
The utility model is achieved through the following technical solutions: it mainly is made up of blower fan and plenum chamber, and the blower fan suction side is communicated with plenum chamber, only it is characterized in that having in this plenum chamber front and the corresponding air inlet of basket buttress runner.
Accompanying drawing 1 is structure, the principle schematic of one of the utility model embodiment.
Accompanying drawing 2 is two structure, the principle schematic of the utility model embodiment.
The basket buttress was piled up schematic diagram when accompanying drawing 3,4 was the gourd, fruit and vegetable precooling.
Among the figure: 1. plenum chamber, 2. blower fan, 3. air inlet, 4. air outlet, 5. baffle plate, 6. sealing strip, 7. air channel, 8. canvas, 9. fruit and vegetable basket.
Describe concrete structure of the present utility model, operation principle and preferred forms in detail below in conjunction with accompanying drawing:
The utility model mainly is made up of parts such as plenum chamber 1, blower fan 2, air inlet 3, air outlets 4.Blower fan 2 can adopt axial fan.If plenum chamber is bigger, when promptly its width was greater than cross section of fluid channel, the plenum chamber front only was provided with air inlet 3 in the centre, and this air inlet should to pile up neatly runner corresponding with basket, and did not establish and the vertical corresponding air inlet of dish basket; In order to reduce floor space, save the space, increase pre-cold, the volume of plenum chamber can dwindle relatively.When its width and cross section of fluid channel when wide, except that the plenum chamber front was provided with air inlet (3), its left and right sides was equipped with air inlet (3).The size of air inlet is by institute's required airflow decision on the plenum chamber.The layout of air inlet should guarantee to make up and down, and intake keeps evenly.When three of plenum chambers were all established air inlet, its back should connect baffle plate 5, and this baffle plate is used for the support to the fruit and vegetable basket, on paste compressible formula sealing strip 6, its position should match with the stud on the fruit and vegetable basket 9, guarantees not leak out between baffle plate and fruit and vegetable basket; Avoid directly entering vertical air quantity of plenum chamber, eliminate the difference of vertical air quantity between each basket without runner.If when plenum chamber only is provided with air inlet in front, can not need baffle plate, and plenum chamber itself promptly can be used as baffle plate (as shown in Figure 2).
On the above-mentioned blower fan 2 air outlet 4 is housed, this air outlet adopts gradually expanded form, in order to reduce local resistance, reduces air loss.
The concrete course of work of the present utility model is as follows: this device is positioned in the freezer, and the fruits and vegetables basket is piled up (as shown in Figure 2) by certain rule.And, prevent to leak out with sealing strip compacting on the muscle of the most close baffle plate fruit and vegetable basket and the baffle plate.At basket buttress upper strata lid canvas 7, build that row's basket bottom away from this device always.Produce negative pressure in the fan operation, plenum chamber, the cold air in the suction freezer.Because this device does not vertically leak out, can make the cold air in the freezer evenly pass through each basket apace, guaranteed the uniformity of each fruit and vegetable basket cooling.The effect of blower fan has further strengthened the cross-ventilation coefficient of heat transfer, has improved heat exchange efficiency, thereby quickens the precooling process of fruit and vegetable.
The utility model compared with prior art has the following advantages and beneficial effect: this device not only can make Basket is piled up neatly the even fast cooling of each several part, has improved the uniformity of each fruit and vegetable basket temperature-fall period, makes melon and fruit, vegetables Good refreshing effect. And compared with prior art, effectively shortened temperature fall time, make each basket temperature fall time poor Be no more than half an hour. So this device energy-wasting is littler, operating cost is lower. In addition, the plenum chamber volume is with existing There is technology to compare relatively and diminishes, thereby reduced floor space, saved the space, strengthened the precooling of fruit and vegetable Amount.
