Abstract

The utility model relates to a chestnut refreshing box with a composite layer, which is characterized in that polyacrylamide fiber cloth is attached to the inner wall of a corrugated box. The utility model can replace the past package bag, and be effective, practical, economic and convenient. The working theory of the utility model is that the utility model uses the heat insulating property, the hygroscopic property and the ventilation property of composite materials to decelerate the awaking time of chestnuts to make the chestnuts slowly switch to a normal temperature state. The utility model can extend the 15 to 20 days of a refreshing time.

Description

A kind of Chinese chestnut antistaling box that has composite bed

Technical field

The utility model belongs to the agricultural products fresh-keeping technology.

Background technology

When Chinese chestnut circulates the field behind fresh-retaining preserving, often go mouldy and speed up, often in 5,7 days short time, just gather mould, just occurred later in 10 days going rotten on a large scale, cause heavy economic losses, and these economic losses are finally born by Li Nong because of the effect of market economy, and Higher output is not accompanied by a higher income to cause Li Nong.Chinese chestnut can produce a large amount of carcinogen aflatoxin in the process of going mouldy simultaneously, also brings very big harm for customer's health.This problem urgently wishes to be resolved.For implementing No. 1 gist of a document of central authorities and resolving three rural isssues and safeguarding the healthy of people, we have carried out the research fresh-keeping to Chinese chestnut.By repeatedly practising and comprehensive many-sided data, think by the Chinese chestnut after the storage, the major cause of accelerating to go mouldy is: no matter 1. the mode of original fresh-retaining preserving how, Chinese chestnut all is in the state of semidormancy between the storage Keeping life, in case broken away from the environmental conditions of former storage, the physiological activity of Chinese chestnut just can be restored rapidly, and respiration is strengthened, revives, germinateed, and this is the natural law of all life continuations.Yet the Chinese chestnut of removing after fresh-keeping does not add any safety method that delays to revive, and often is again the season that Chinese chestnut begins growth of future generation at this moment, so physiological activity is stronger, breathes more prosperously, leads to acceleration and goes mouldy.2. the mode that has adopted inappropriate packing or continued to preserve causes generating heat (boiling in a covered pot over a slow fire), going mouldy with second duration of storage in transit rotten.When circulating the field, Chinese chestnut mostly adopts gunnysack, woven bag, mesh bag or plastic bag.No matter when being that a kind of packing stack up, because respiration heat and external environment that Chinese chestnut produces just can form certain heal differential, promptly pile the temperature height of the inside, the temperature of out-pile face is low, when the hot gas of heap the inside during to external diffusion, just can condense into water droplet at the cold and hot interface of Chinese chestnut heap owing to the reason of heal differential, this natural phenomenon is commonly referred to dewfall.Dew can be built the environment that growth is germinateed for Chinese chestnut, and the condition of regeneration and breeding also is provided for germ, and its result just quickens to go mouldy rotten.

The content of invention

The purpose of this utility model provides a kind of Chinese chestnut antistaling box that has composite bed, substitutes packaging bag in the past, not only effectively but also practical, and not only economy but also convenient.Its principle is to utilize the thermal insulation of composite material, hygroscopic property, and permeability to air slows down the recovery time of Chinese chestnut, makes its forwarding under the normal temperature state slowly, reaches and delays to go mouldy generation.

The technical solution of the utility model is: a kind of Chinese chestnut antistaling box that has composite bed is characterized in that: be attached with the polyacrylamide fiber cloth on the inwall of corrugated case.

Aforesaid antistaling box is characterized in that: the polyacrylamide fiber cloth of adhering on the inwall of corrugated case is attached on the inwall of corrugated case by adhesives glue.

The principle that the composite bed continuity is fresh-keeping

Based on the above-mentioned acceleration Chinese chestnut rotten reason of going mouldy.We think the continuity dormant state, slow down recovery time, and the time expand that its respiratory intensity is grown from weak to strong just can solve the problem of going mouldy fast.Studies show that the packing chest that adopts a kind of liner composite bed, substitute packaging bag in the past and be a kind of not only effectively but also practical, not only economy but also method easily.Its principle is to utilize the thermal insulation of composite material, hygroscopic property, and permeability to air slows down the recovery time of Chinese chestnut, makes its forwarding under the normal temperature state slowly, reaches and delays to go mouldy generation.

This composite material is a polyacrylamide cloth, and is nontoxic, pollution-free.Polyacrylamide has less coefficient of thermal conductivity, so can play the heat-insulation and heat-preservation effect, is unlikely after in Chinese chestnut is packed case into the environment conditional mutation takes place, temperature traverse particularly, to be slowly from low to high, and reach thereafter and extraneous thermal balance, thereby prolong the rest period of Chinese chestnut; This material has bigger hygroscopic property, certain respiration heat can be because of the heal differential dewfall yet even Chinese chestnut has recovered physiological respiration effect generation, because the gaseous pressure when producing heat energy in the case is wanted height a bit comparatively speaking, when humid gas spreads towards periphery and composite bed intersect and just to be absorbed by the strong hygroscopic property of this material, thereby both solved the harm that is condensed into water and also safeguarded the interior gas equilibrium of case, make the relative air humidity in the case keep lower level, also take place because of the problem stratification of moisture and the situation of microbial reproduction with regard to having avoided above-mentioned.

Description of drawings

Fig. 1 is the casing cutaway view of the utility model embodiment.Wherein, 1 antistaling box, 2 corrugated cases, 3 polyacrylamide fiber cloth.

Concrete embodiment

Embodiment of the present utility model is attached to polyacrylamide fiber cloth 3 usefulness adhesives glue on the inwall of corrugated case 2 as shown in Figure 1, is the antistaling box 1 that has composite bed.Adhesives can be used converted starch.

Treat that Chinese chestnut is packed into and just can realize delaying the time that Chinese chestnut revives with the adhesive tape sealing behind the case.Adopt this antistaling box that has composite bed can prolong storage period 15～20 days.

Claims

1, a kind of Chinese chestnut antistaling box that has composite bed is characterized in that: be attached with the polyacrylamide fiber cloth on the inwall of corrugated case.

2, antistaling box as claimed in claim 1 is characterized in that: the polyacrylamide fiber cloth of adhering on the inwall of corrugated case is attached on the inwall of corrugated case by adhesives glue.
