Abstract
The utility model relates to an instrument for quickly analyzing microbial activity of agricultural product. Detection in prior art has low accuracy, and instrument has poor use safety and short service life. The reaction tank of the instrument for quickly analyzing microbial activity of agricultural product is provided with a heating pipe with dry-burning preventing device, temperature control is accurate, and the dry-burning accident of equipment can be avoided. A gas sensor is connected with an air tap via a ventiduct and arranged on a position above the air tap, the gas sensor is avoided the condensation, accumulation and direct effect of water vapor, the service life of the gas sensor is extended, and detection accuracy is raised. A central processing unit controls the operation of every component, and the reliability of equipment is increased. All detection results and parameters can be clearly displayed in a display screen, operation parameters can be previously input by a keyboard, and the whole operating process is simple and quick.
Description
Technical field:
The utility model relates to a kind of detecting instrument of microbial activity value, especially relates to a kind ofly detecting that contained microorganism grows in the agricultural product, the instrument of activity situation during agricultural storage.
Background technology:
Microorganism grows in agricultural product, breeds, and can decompose, utilize the composition in the agricultural product, secretes various metabolic products, thereby destroys the quality of agricultural product; Even more serious is, and many microorganisms can secrete the material that produces toxic effect, as aflatoxin etc., can have a strong impact on human foodsafety.In order to prevent the harm of microorganism to agricultural storage, present national grain depot is to utilize the activity of measuring method of temperature monitoring microorganism, and has been equipped with the development of treatment facilities inhibition microorganism in grain storage such as grain storage ventilating system, cereal cooling system.But, the temperature monitoring method of microorganism is sensitive inadequately, and when the grain storage temperature had ANOMALOUS VARIATIONS, microorganism is raised growth, breeding, take to ventilate in this period, cooling measure can only work to stop further harm of microorganism, it is irreversible to harm that reserve produces.Therefore, effectively protect the storage quality of agricultural product, guarantee to store the relevant foodsafety of agricultural product, key is that reliable, sensitive microorganism detection method will be arranged, and especially can accurately detect the method for microorganism physiological activity state.
The method of traditional detection microorganism content of molds can not reflect the physiologically active state of microorganism, especially can not judge effectively whether mycotic spore is in the growth or the metabolism state of harm quality of agricultural product, and detect length consuming time, can not provide the decision-making foundation of science for effective use antibacterial, the mildew-resistant technology.
Though the fast measuring instrument of contained microorganism can carry out the fast detecting of content of microorganisms in the existing grain storage, but place the retort outside can not accurately control temperature owing to will heat with thermostatic element, have a strong impact on the sensitivity and the degree of accuracy of measurement, and operation of equipment is loaded down with trivial details, sensor is directly installed on the retort, be subject to the influence of steam, reduce the life-span of accuracy in detection and shortening gas sensor.
The utility model content:
The purpose of this utility model is to remedy weak point of the prior art, and a kind of instrument that can fast, accurately detect the high stability of agricultural product microorganism amount and physiological activity situation thereof is provided.
Concrete technical scheme of the present utility model is as follows:
The utility model is made of a casing, retort is installed in casing, casing and reaction cover air-tight fit are passed in the retort upper end, the retort side is equipped with the heating tube of valve, temperature sensor and tool anti-dry function, valve through snorkel be installed on the gas sensor that is higher than the valve position and link; A magnetic stirring apparatus is installed in the retort below, and magnetic stirring bar places the retort bottom; At box house central processing unit is installed, supervisory keyboard and display screen is arranged in the mounted on surface of casing; Link with the central processing unit joining gas detection line other end and gas sensor, link with the central processing unit joining thermometric sense line other end and temperature probe, link with the heating tube of the central processing unit joining temperature control line other end and tool anti-dry function, link with the central processing unit joining stirring control line other end and magnetic stirring apparatus, link with joining keyboard transmission line of central processing unit and supervisory keyboard, link with the central processing unit joining demonstration transmission line other end and display screen; Discharging tube is equipped with in the retort bottom, and the other end of discharging tube links with the valve that is fixed on the casing side.
Principle of the present utility model is:
But there is the mould decomposition of hydrogen peroxide of harm influence to produce oxygen to quality of agricultural product, and the oxygenous ability of decomposition of hydrogen peroxide has the raising of highly significant when mould enters growth conditions or physiological metabolism active state, utilize gas sensor to detect the amount of oxygen of generation, marking current is changed through A/D, can demonstrate measured value in display screen.
Advantage of the present utility model is:
1, the heating tube of the utility model mounting strap anti-dry burning device in retort, improved the efficiency of heating surface, reduced the thermal inertia of heat temperature raising, make the temperature precise control, can avoid equipment generation dry combustion method accident, thereby the accuracy of detection and security, the reliability of instrument use are all improved greatly.
2, the utility model connects by snorkel gas sensor with valve, be installed on the position that is higher than valve, can avoid steam in gas sensor, to condense, accumulate, and be subjected to directly influencing of steam, improve the serviceable life and the detection accuracy of gas sensor.
3, the utility model central processing unit is controlled the operation of each parts, has increased the reliability of equipment greatly; All testing results and parameter can clearly illustrate in a display screen that operational factor can be imported setting in advance by keyboard, the simplified operation process.
