Abstract
The invention discloses a kind of agent for storage of coldness, by weight percentage, includes water swellable cellulose, 7 25% chloride, 0.1 0.7% additive and 2 7% alcohols of 1 10% drying, remaining is water.On the premise of cellulose containing swellability, alcohols is added, accelerates the formation of gel colloidal.The agent for storage of coldness cooling time of the present invention is short, cold insulation time length；The formula used is simple and easy to get；It is green, non-toxic；Technique is simple, low manufacture cost.
Description
Technical field
The present invention relates to agent for storage of coldness, more particularly to a kind of cool-storage time is long, the agent for storage of coldness of nonhazardous.
Background technology
With the development and the improvement of people's living standards of science and technology, long-range low temperature conveying fresh food, medicine etc. are more next
More welcome, therefore, Cool Storage Technology is more and more concerned, and Cool Storage Technology is to utilize the effective means such as various physics, chemistry, machinery
Cold is stored in agent for storage of coldness, it is necessary to when the process that again discharges the cold of storage.Produced by the technology
Cold can be efficiently stored, meets various physics again, this material of chemical requirements is referred to as agent for storage of coldness.
But current agent for storage of coldness using inorganic salts, alcohols and the silver iodide for core agent, copper sulfide, xanthans, α-
Azophenlyene, sodium pyrophosphate etc., freeze-off time is long, the cold insulation time is short, and introduces substantial amounts of industrial chemicals, can not accomplish it is nontoxic, such as
Agent for storage of coldness is revealed in fruit transportation, contaminated food products or medicine, can cause serious consequence.
The content of the invention
Goal of the invention：The invention provides a kind of agent for storage of coldness, the agent for storage of coldness solve existing agent for storage of coldness freeze-off time it is long,
The problem of cold insulation time is short；Meanwhile solve the problems, such as that existing agent for storage of coldness toxicity is big.
Technical scheme：The agent for storage of coldness of the present invention, by weight percentage, including the water swellable cellulose of 1-10% dryings,
The alcohols of 7-25% chloride, 0.1-0.7% additive and 2-7%, remaining is water.Before cellulose containing swellability
Put, add alcohols, accelerate the formation of gel colloidal.
Optimum ratio：By weight percentage, including 2-5% dry water swellable cellulose, 10-17% chloride,
0.2-0.5% additive and 4-6% alcohols, remaining is water.
In order to ensure the hardness and cold insulation duration after agent for storage of coldness freezing, in the agent for storage of coldness, dry water-swellable is fine
Viscosity after dimension element swelling is to show 2000-4000mPas.
The water swellable cellulose is hydroxyethyl cellulose, carboxymethyl cellulose, hydroxypropyl methyl cellulose and methyl
One or more in cellulose.
The chloride is the one or more in sodium chloride, potassium chloride and ammonium chloride.
The additive is the one or more in flavoring essence, food coloring and preservative.
The alcohols is the one or more in ethanol, ethylene glycol and isopropanol.
Beneficial effect：1st, agent for storage of coldness cooling time of the invention is short, cold insulation time length；2nd, the formula used is simple and easy to get；
3rd, it is green, non-toxic；4th, technique is simple, low manufacture cost.
Embodiment
Embodiment 1
