Description
Technical field
The present invention relates to food sterilizing technical fields, more particularly, to a kind of fluid bed powder continuous sterilization device.
Background technology
Food sterilization is exactly using raw-food material, processed goods as object, by causing the micro- life of the principal element of food spoilage
The sterilization and degerming of object, reach the stabilisation of food quality, effectively extend the shelf-life of food, and therefore reduce in food and be harmful to
The amount of survival of bacterium, the bacterium for avoiding the intake of viable bacteria from causing human body (being typically enteron aisle) infection or generated in food in advance
Toxin leads to human poisoning.Existing food sterilization mode is varied, but for the sterilization mode master of powder type food
To use microwave disinfection mode and irradiation sterilization mode.
Microwave frequency of the microwave disinfection mode for sterilization is 2450MHz, and result of study generally believes microwave to microorganism
Lethal effect have the factors of 2 aspects, i.e. fuel factor and non-thermal effect.Fuel factor refers to that material absorbs microwave energy, makes temperature
It increases to achieve the effect that sterilizing.And non-thermal effect refers to polar molecule in organism generates strong rotation in microwave field
Turn effect, this strong rotation makes the enzyme system that the vegetative cell of microorganism is lost activity or destroyed in microbial cell, makes
At the death of microorganism.Microwave disinfection has the characteristics that penetration power is strong, energy saving, the efficiency of heating surface is high, applied widely, and
Microwave disinfection is convenient for control, and homogeneous heating, the nutritional ingredient and color of food are after sterilization still close to the natural product of food
Matter all contains abundant protein in most foods at present but a disadvantage is that being easy to make protein denaturation in food, this is also people
Class needs the Major Nutrient absorbed, that is to say, that microwave heating can destroy food nutrition to a certain extent, this is lacking for it
Point.
Irradiation sterilization mode be exactly using X-ray, gamma-rays or accelerate electron ray (most commonly seen be Co60 and
The gamma-rays of Cs137) to the penetration power of food with reach kill microorganism in food and insect pest a kind of sterilization method.By
The food of irradiation or organism can form ion, excited state molecule or molecular fragment, and then interact again between these products, raw
At the compound different from hyle, on the basis of chemical effect, also occurred that by irradiation material or organism a series of
Biological effect, so as to cause in pest, worm's ovum, microbial body protein, nucleic acid and promote the enzyme of biochemical reaction by broken
It is bad, lose vigor, and then terminate the process that agricultural product, food were etched and grows aging, maintenance stay in grade.Combine within 1980
Food and agricultural organization of state (FAO), International Atomic Energy Agency (IAEA) and (WHO) the joint specialist committee of the World Health Organization, it is proposed that
" with any food of 10KGY or less dose deliveries, all without problem in terms of toxicology, it is not necessary that carry out toxicology test "
It is recommended that worldwide advance commercial applications of the irradiation in food production.But irradiation sterilization mode has very
Big limitation：(1) investment is big.Special equipment is needed to generate radiation (radiation source), and safety prevention measure is provided, to protect
Card radiation is not revealed；(2) under high dosage irradiation sensory properties disadvantageous changes；(3) acceptance：Due to the history of various countries, life
Custom and regulation difference living, allow the food variety still difference of irradiation larger, majority state requires irradiated food in the world at present
It especially to be marked on label.
It can be seen from the above, the sterilization mode of existing powder food has significant limitation, and existing sterilization method is mostly
Using intermittent sterilization method, sterilizing efficiency is slow, therefore, it is necessary to it is good and efficient to develop a kind of sterilization effect, and at
This low, easily operated sterilizing installation.
