Description

A kind of food safety detection sampling box

Technical field

The utility model relates to the food safety detection utensil, relates in particular to a kind of food safety detection sampling box.

Background technology

In food safety detection work, often some perishable food are carried out the harmful microorganism check, as the barbecue meat in the meat products, sauce halogen meat; Ice cream in the cold drink food etc.; In addition, when handling food poisoning, also need to gather suspect food and test.Because check relates to the pathogenic microorganisms index, the pathogenic microorganisms content in order to make in the sample thief is accurate, so just need make microorganism wherein be in dormant state to the on-the-spot sample of adopting, stops to breed, and just need change accumulating under 0-4 ℃ the condition immediately over to.Present case is: some supervision units are from being supervised the sample of unit collection in worksite, the common polybag of packing into is transported to the laboratory, sometimes once need collected specimens more, road is far away, add the handing-over time of sample, the sample of gathering needed 8-12 hour just can enter the laboratory, because the time from the sample collecting to the laboratory is longer, microbial reproduction is fast again, especially in summer, microorganism in the sample breeds in a large number, sample contains the living bigger error of pathogenic bacteria volume production when result of laboratory test that makes and collection, cause by the qualified Food Inspection result of supervision unit original pathogenic bacteria index defectively, had a strong impact on the legal effect of testing result, even caused the dispute with supervisory organ by the unit of supervision.

The utility model content

The technical problems to be solved in the utility model provide a kind of without power drive, simple in structure, easy to use, price is low, and go at sample collecting and to satisfy a kind of food safety detection sampling box that the contained pathogenic microorganisms of sample is in thalline dormancy shape in the process of laboratory.

In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: this a kind of food safety detection sampling box is made of casing, case lid, sample retention chamber, it is characterized in that: have two-layer around case lid and the casing, skin is a stainless sheet steel, admittedly act on to play frame, nexine is a heat-insulation layer; To prevent exchange heat inside and outside the casing, there are three layers at the bottom of the case, skin is a stainless sheet steel, near stainless sheet steel is heat-insulation layer, one deck is a heat-insulating shield, a cavity is arranged between heat-insulating shield and heat-insulation layer, the refrigerator cool storage container that is used to pack into, the centre is the sample retention chamber, and bracing frame is arranged in the sample chamber, be placed with 6-9 the netted space that is connected as a single entity on the bracing frame, place sample in the netted space, be beneficial to heat interchange, have 4-5 exchange hole at the bottom of the case on the heat-insulating shield, blocking up on the heat interchange hole has temp autocontrolled retaining door, and the heat interchange in the sample chamber is undertaken by the heat interchange hole.The utility model is also implemented by following measure: temp autocontrolled retaining door is made by the thermometal sensing chip, one side of temp autocontrolled retaining door is fixed on the one side in heat interchange hole by rotating shaft, another side is by being attached on the heat-insulating shield, when the temperature in the sample retention case is higher than 3 ℃, rising along with temperature, open gradually on the open limit of temp autocontrolled retaining door, cold air in the folder chamber just enters the sample storage bin from the heat interchange hole and carries out convective exchange, when the temperature in the sample chamber is lower than 3 ℃, reduction along with temperature, the open limit retraction of temp autocontrolled retaining door is blocked the heat interchange hole by being attached on the heat-insulating shield, stops the cold air convective exchange.Thereby the temperature that has reached food samples preservation case remains on 0-4 ℃, guarantees that the pathogenic microorganisms in the sample is in dormant state.In addition, also be provided with viewport and hand-strap on the casing.

The beneficial effects of the utility model are: this a kind of food inspection sampling box is simple in structure, making is easy, cost is low, easy to carry, and need not any power drive, the temperature of food samples just remains on 0-4 ℃ microorganism dormancy state in the sample chamber, has guaranteed the accuracy of assay.Can be widely used in the detection sampling work of food security.
