Description
Technical field:
The present invention relates to cereal deinsectization method, specially a kind of low-temperature frozen melts deinsectization method.
Background technique:
In the overall process of foodstuff preservation, pest problem should be all noted that at any time from beginning to end.Slightly neglect, it is possible to
Cause pest mass propagation to cause harm to cause damages.Therefore we should follow a principle just in grain storage pest controlling work
It is " putting prevention first ", reason is very simple, because cannot seriously occur until pest, grain is during foodstuff preservation
It is subjected to going to wipe out and treat insect pests and plant diseases again when heavy losses.And should pay attention to no worm grain taking insect prevention measure, prevent pest intrusion grain numerous
It grows and causes harm.There is the grain of a small amount of pest for discovery, according to circumstances should take measures as early as possible, thoroughly wipe out and treat insect pests and plant diseases pest, make it will not
Mass propagation causes harm, in this way, also just playing anti-effect.
It is current using the pest in the condition of winter and spring natural low temperature kill grain storage, packaging equipment, storage apparatus
The main method of low-temperature insecticidal.China northeast, North China and northwest wide geographic area application low temperature prevent and treat grain storage pest, there is significant effect
Fruit；Opportunity also may be selected in southern area, and reducing grain temperature using winter, autumn, spring cold current can have although cannot kill off the insect pests
Effect ground inhibits the vital movement of pest, reduces the algebra of pest breeding, and the time retardation for occurring that pest largely 1-2 months, this
Sample can still reduce the loss of grain.Frozen insecticide according to local circumstance can take outside storehouse freezing, in storehouse inside and outside freezing or storehouse
The method that freezing combines carries out.But existing deinsectization mode is for food by multigelation, i.e., it is enabled to remove some post
Infested larva, but the quality decline of cereal is caused, it influences to eat.
So how to design a kind of low-temperature frozen melts deinsectization method, becoming us will currently be solved the problems, such as.
Summary of the invention:
It is above-mentioned to solve the purpose of the present invention is in view of the drawbacks of the prior art, providing a kind of low-temperature frozen to melt deinsectization method
The problem of background technique proposes.
To achieve the above object, the invention provides the following technical scheme: a kind of low-temperature frozen melts deinsectization method, including dedusting
Machine, dryer and low-temperature frozen melt insecticidal box, this method are as follows:
Step 1: being put into dust removal machine for cereal and be dusted, and removes impurity and sludge；
Step 2: extra water is dried when the cereal after dedusting is put into dryer to dedusting；
Cereal after drying: being put into the low-temperature frozen and melted in insecticidal box by step 3, and the low-temperature frozen is melted insecticidal box from 0
Subzero 18 degrees Celsius degree Celsius are dropped to, the used time 3 hours, cooling extent was average 6 degree or so per hour, up to temperature drops to
Subzero 18 degrees Celsius；
Step 4: after temperature is down to subzero 18 degrees Celsius, start rewarming, temperature restores 4 degrees Celsius, and subzero 18 degrees Celsius extensive
4 degrees Celsius in return-to-zero, time 1 hour used in rewarming；
Step 5: the circulation of repetition step 3 and step 4 is twice；
Step 6: by being stored at room temperature food after two circulations.
As a preferred technical solution of the present invention, temperature fall time should be 3 in each circulation in the step 2
Hour, temperature not decline too fast, otherwise will affect to insect fragmentation effect.
As a preferred technical solution of the present invention, rewarming time should be 1 in each circulation in the step 4
Hour, temperature not decline too fast, otherwise will affect to insect fragmentation effect.
As a preferred technical solution of the present invention, the low-temperature frozen melt insecticidal box carry out freeze thawing method twice can be with
The insect to live close in 90% cereal and worm's ovum are killed, 85% Parasite larvae in fresh food materials can be killed, obtain 60%
The bacterium of left and right, can extend the food holding time.
As a preferred technical solution of the present invention, the low-temperature frozen melts insecticidal box and carries out the method solution of freeze thawing twice
Food passes through the problem of multigelation quality decline, and freeze thawing twice, and retains the quality of food materials to greatest extent.
The beneficial effect that low-temperature frozen of the present invention melts deinsectization method is:
This method not only kills 85% helminth in the insect to live close in 90% cereal and worm's ovum and fresh food materials
Larva, and solve the problems, such as food by multigelation quality decline, and to greatest extent using the method for freeze thawing twice
Retain the quality of food materials.
Specific embodiment:
The preferred embodiments of the present invention will be described in detail below, so that advantages and features of the invention can be easier to by this
Field personnel understanding, so as to make a clearer definition of the protection scope of the present invention.
The present invention provides a kind of technical solution: a kind of low-temperature frozen melts deinsectization method, including dust removal machine, dryer and low-temperature frozen
Melt insecticidal box, this method are as follows:
Step 1: being put into dust removal machine for cereal and be dusted, and removes impurity and sludge；
Step 2: extra water is dried when the cereal after dedusting is put into dryer to dedusting；
Cereal after drying: being put into low-temperature frozen and melted in insecticidal box by step 3, and low-temperature frozen is melted insecticidal box under 0 degree Celsius
Subzero 18 degrees Celsius are down to, the used time 3 hours, cooling extent was average 6 degree or so per hour, until temperature drops to subzero 18 and takes the photograph
Family name's degree；
Step 4: after temperature is down to subzero 18 degrees Celsius, start rewarming, temperature restores 4 degrees Celsius, and subzero 18 degrees Celsius extensive
