GB/T 22184-2008/ISO 4112.1990IntroductionFood stored in large quantities because of their physiological activities will generate heat. Hot food will make the temperature rise, leading to commercial-quality food, Quality and food quality process irreversible deterioration. Therefore, we must constantly monitor changes in food storage temperatures and overheating of food Ventilation and refrigeration and other food to take immediate measures to cool. In the grain stored in bulk, the heat hazards in the initial stages is usually localized and affect only a small part of the stored grain. If not in time, will their Some of his spread. Although only partial heating of food, its consequences are serious. It will lead to lower prices of processed food in bulk or simply can not sell Out. In order to maintain food quality and extend the shelf life of food, frequently check the temperature of food it is very necessary. For this purpose, the base In a large number of measurement points of temperature monitoring is an appropriate technology. For proper ventilation cooling, the thermometer is also required. In cold weather, the grain temperature can be gradually reduced to 5 ℃ ~ 7 ℃. At 0 ℃, even if the water reaches the highest internationally recognized limit physical activity to food is also very weak. GB/T 22184-2008/ISO 4112.1990 Cereals and legumes Food stored in bulk temperature measurement guide1 ScopeThis standard specifies the Silos and other grain stored in silos scattered temperature measurement guidelines.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Grain cereals and legumes. 2.2 A lot of food stored in the warehouse in a non-packaged form. Principle 3 Place a series of temperature probes in grain stored in bulk in order to monitor or monitor temperature changes.4 InstrumentAccording to the size and shape of the granary, select the appropriate thermometer (system) and install the form. Common are. --- Portable instrument small barn used; --- Semi-fixed or telescopic instrument used WAREHOUSE; --- Silos using stationary equipment. Thermometer (system) consists of the following components. 4.1 Temperature Probe Usually it consists of one or more of the tube or cable (4.1.1) and one or more temperature sensing devices (4.1.2) and their external wire group Into these wires should be set into the tube or cable. When the detector buried in a pile of grain, it reaches a stable temperature readings should not exceed 3min. Making the detector material should be fumigated anti-corrosion and to prevent rodent damage. Machine with a grain warehouse WAREHOUSE should configure flexible temperature probe. Note 1. Silos in the suspension cables should be fixed in the warehouse at the end, in order to prevent displacement during loading. 4.1.1 tube or cable wrapping materials. glass fiber, metal or other suitable material are suitable pipe length and diameter. use In silo tubes should have a certain strength and rigidity to resist Jincang food, a lot of tension and pressure generated when the warehouse. Note 2. the role of the pipe or cable force with its diameter, depth and the laying of handling mobile food varies, the maximum pull up more than 50kN. Small The diameter of the tube can be reduced and simplified fixing point tension fastening system, the tube has a greater diameter greater rigidity, suitable for high granary. 4.1.2 temperature sensing device (thermal sensor). includes a thermistor or thermocouple or impedance thermometer, or any other, can detect Electronic temperature sensing device temperature 0.5 ℃ change, and its scope of work to the local environment should be 70 ℃ minimum temperature. 4.2 temperature indicator May be accompanied by a recorder (see Appendix A).
