Abstract

The utility model provides a vegetable seed sterilizer comprising two parts including a liquid sterilization part and a heating sterilization part. A liquid sterilization groove is internally filled with a sodium phosphate solution with the concentration of 10% so as to inactivate viruses on the surfaces of seeds. The heating sterilization part is formed by seven parts including a draught fan, a material platform, a feeding opening, a temperature sensor, a hot blast heater, a fan and a temperature controller. After being subjected to liquid sterilization treatment, vegetable seeds are placed on the material platform; and the hot blast heater heats and the fan blows hot air to the material platform to heat the seeds to kill pathogenic microorganisms carried by the seeds. The seed sterilizer is simple in structure and flexible in use, can effectively kill the pathogenic microorganisms carried by the vegetable seeds and has smaller influence on seed germination rate.

Description

A kind of vegetable seeds sterilizing machine

Technical field

The utility model belongs to the agricultural seed process field, relates to a kind of disinfector of seed, specifically the vegetable seeds sterilizing machine.

Background technology

Vegetable seeds is the pathogenic microorganisms such as subsidiary virus, fungi easily, invade seedling with seed germination, seedling, affect growth of seedling.Thereby, before the vegetable seeds plantation, vegetable seeds is carried out disinfection, can avoid to a certain extent the generation of seed-borne disease.In disinfecting process, as far as possible that seed is subsidiary most pathogenic microorganisms kill on the one hand, as far as possible percentage of seedgermination are not had impact substantially again simultaneously.Existing seed disinfection device is mainly by the heat-killed fungal spore, lacks not only for fungal spore, but also for the chlorination equipment of Seed-borne Virus.

Summary of the invention

The purpose of this utility model is in order to solve the vegetable seeds sterilization problems, and a kind of vegetable seeds sterilizing machine is provided, can be fast, convenient, kill pathogenic microorganism subsidiary in the vegetable seeds efficiently.

The purpose of this utility model is achieved in that the vegetable seeds sterilizing machine comprises liquid disinfection and heating disinfection two parts.10% sodium radio-phosphate,P-32 solution is housed in the liquid disinfection groove, but the virus of deactivation the surface of the seed.The heating disinfection part is comprised of air-introduced machine, material table, charging aperture, temperature sensor, hot-blast stove, blower fan, temperature controller seven parts.Vegetable seeds is put to material table after liquid disinfection is processed, the hot-blast stove heating, and blower fan blows hot-air to material table, and seed is heated to kill the pathogenic microorganism that seed carries.

Advantage of the present utility model and effect:

1, can effectively kill the pathogenic microorganism that vegetable seeds carries, less on the percentage of seedgermination impact simultaneously;

2, simple to operate, common staff can finish through simple training.

Description of drawings

Accompanying drawing 1 is the structural representation of vegetable seeds sterilizing machine.Among the figure, 1 air-introduced machine, 2 temperature sensors, 3 material tables, 4 charging apertures, 5 hot-blast stoves, 6 temperature controllers, 7 blower fans, 8 liquid disinfection grooves.

Embodiment

The using method of vegetable seeds sterilizing machine is as follows:

1, the vegetable seeds adding is placed with in the liquid disinfection groove of 10% sodium radio-phosphate,P-32 solution, soaks 20 min;

2, vegetable seeds is taken out from the liquid disinfection groove, water is drained by being put to material table by charging aperture, start hot-blast stove, blower fan blows the hot-air that hot-blast stove produces to material table, and with the seed heating, air-introduced machine siphons away unnecessary air simultaneously; Utilize temperature sensor monitors material table temperature variations, utilize the startup of temperature controller control hot-blast stove and close 70 ℃ of control material table temperature maintenances;

3, with vegetable seeds 70 ℃ of processing 6 h on material table, close hot-blast stove, after the vegetable seeds temperature is down to normal temperature, take out, namely finish sterilization.

Claims

1. vegetable seeds sterilizing machine, comprise liquid disinfection and heating disinfection two parts, 10% sodium radio-phosphate,P-32 solution is housed in the liquid disinfection groove, but the virus of deactivation the surface of the seed, the heating disinfection part is by air-introduced machine, material table, charging aperture, temperature sensor, hot-blast stove, blower fan, temperature controller seven parts form, vegetable seeds is after liquid disinfection is processed, put to material table, the hot-blast stove heating, blower fan blows hot-air to material table, and seed is heated to kill the pathogenic microorganism that seed carries, this seed disinfection machine is simple in structure, use flexibly, can effectively kill the pathogenic microorganism that vegetable seeds carries, less on the percentage of seedgermination impact simultaneously.
