The decision of agricultural problems with beetles pests when sending solid grains for long term storage

Problems

Insect pests are a great danger to agriculture all over the world. The extent of this risk can be presented on the basis of the data contained in the materials of the FAO World Food Organization to the United Nations (FAO): statistics on the earth's surface hectare falls: 0.2 - 0.5 kg birds, 2 - 3 kg of rodents, 15 of mammals and 300 kg kg (!) insects. The current state of the rice warehouse in Southeast Asia (especially Indonesia) is such that to be put on long-term storage of large central warehouses rice exposed to infection beetles pests in large numbers because of a favorable environment for their reproduction

 

 

 

 

 

 

 

The existing method of struggle

The most common method of struggle is fumigation / aeration - a method of disinfection, pest and rodent control measures associated with the destruction of pests and plant pathogens by poisoning them with toxic vapors or gases.
Unfortunately fumigation was not so effective solution for the control of pests in storage. Because rice is packaged in bags of 45-50kg and bags stacked on pallets at a height of about 6 meters, storage space is not sealed, that provide high-quality processing of products by this method is not possible. Most beetles retain the possibility of reproduction, which leads to increase in the next population.
Fumigation in similar stores in Southeast Asia carried out every 3 months, entailing considerable financial costs and relative effectiveness.

 

 

 

 

 

 

 

Nonchemical method of disinfestation of grain

An alternative method of pest control is the treatment with ionizing radiation for the purpose of sexual sterilization, so-called non-chemical or clean technology, as it is not used to achieve the goal of any chemistry.
The doses required for the sexual sterilization of beetles, too small (100-300 Gy), which allows greatly reduce grain processing time ensuring a high processing speed.
Negative impact on the grain in such a treatment is not provided, bugs completely lose their reproductive function, and when crossed with healthy individuals also do not produce offspring that effectively affects the sharp decline in the total population.
The high penetrating power of ionizing radiation makes it easy to handle and pests inside the bag that allows you to completely destroy the population.

  1. Prepared for long-term storage in bags rice supplied to the temporary storage
  2. Then the bags of rice are processed by gamma radiation before storage
  3. Past treatment products are sent to the store prepared for storage

 

 

 

 

 

 

A general view of a typical gamma-installation with the sources of ionizing radiation Co-60

Technical characteristics of gamma-installation

According to the request of "NTB" Radtehproekt "(Supplier) together with the Customer can create an industrial-scale plant designed for the sterilization of medical supplies and food products placed in boxes. Installation - the irradiation chamber with radiation protective concrete walls with a water basin to accommodate the exciter radiation sources and equipment, ensuring the delivery of radiation to the area and radiation processing of products with specified characteristics of Radiation-technology. The plant provides uninterruptible power supply system of the executive equipment with a diesel generator, which provides continuous operation of the plant at the time of a power outage.

Main specifications:
• radiation source - cobalt-60.
• initial activity feed - 350 ± 10% kCi. (12.95 * 1015 Bq).
• Maximum capacity of the irradiator - 2000 kCi.
• irradiator - planar, two-piece (~ 76 channels to download sources).
• irradiation facility - cereals, packaged in sacks and stacked on pallets.
• minimum absorbed dose - 100-300 Gy (disinfestation of grain).
• maximum absorbed dose - 30 kGy (for sterilization of medical products).
• Use emission factor (calculated) - 22%.

Installation management and security system

Process control system is designed for automated inspection and process control exposure line at the facility with Co-60 radionuclide sources of ionizing radiation.

APCS is a two-level hierarchical system. The system includes the following structural elements:
- On the lower level:
cabinet power automation (hinge connected buses)
wardrobe programmable logic controller (SHPLK)
- On the upper level:
workstation (AWS).

install security system
Security gamma setup performed based on the requirements of the "Basic sanitary rules of radiation safety (OSPORB-99/2010)," Radiation Safety Standards "(NRB-99/2009), developed by the Ministry of Health of Russia These rules are based on the following regulations.: International Basic safety Standards for protection against ionizing radiation and for the safety of radiation sources, adopted jointly by the Food and Agriculture Organization, the International Atomic energy Agency, the International Labour Organization, the Agency for vigorous energy of the Organisation for economic cooperation and development, Pan American health Organization and the World health Organization (safety series number 115), 1996
