Description

A vegetable seed dryer suitable for medium and small samples

technical field

The utility model relates to a device suitable for rapid drying of medium and small sample vegetable seeds, in particular to a device for quickly and fully drying vegetable seeds by using circulating air at a constant lower temperature (in order to ensure that the vitality of the seeds is not affected). Dry equipment.

Background technique

At present, during the breeding process of vegetable breeding units, especially fruit vegetables such as cucumber, watermelon, pumpkin, loofah, bitter gourd, muskmelon, zucchini, gourd, gourd, tomato, eggplant, pepper and other seeds have high water content after maturity. It is often necessary to wash to remove the adherents on the surface of the seeds and some of the deflated seeds. The water content of the seeds and their surfaces is relatively high; there are thousands or thousands of copies of each vegetable crop breeding material in each production season, and most of them after washing Nylon seed bags are used to dry naturally. Each seed bag holds a portion of material or a strain. If there are a little more seeds in a seed bag or a little more seed bags hanging on a hanging pole or in rainy weather, the seeds will be dried in the sun. Insufficient, easy to mold, germination or rotten seeds, resulting in low seed germination rate.

The utility model uses circulating air to quickly and fully dry freshly picked vegetable seeds at a constant lower temperature, and is especially suitable for breeding units to dry large batches of medium and small samples of seeds, while ensuring that samples will not be confused.

Utility model content

Aiming at the problem of small sample size, large number of samples, and lack of suitable drying machinery for vegetable seeds, especially fruit vegetable seeds, in breeding units, the freshly harvested vegetable seeds are quickly dried under the premise of ensuring seed vitality to ensure seed quality. The utility model provides a seed drying machine, which mainly solves the problem of rapid and sufficient drying of fresh vegetable seeds, especially fruit and vegetable seeds in different seasons and different weather conditions.

The technical scheme that the utility model solves its technical problem adopts is:

A seed dryer suitable for small samples of fruits and vegetables, characterized in that it comprises: a cabinet body, which is an installation carrier for other components, and the walls of the cabinet body are provided with insulation layers and insulation layers. The cabinet body includes a main space and an openable door body, and an air outlet is arranged on the bottom plate of the cabinet body. There are at least three sets of electric heating tubes on the left and right side walls and the upper, middle and lower parts of the rear wall, and a control panel (including temperature, humidity, time, motor power and fan power) is provided on the upper part of the cabinet to control the work of internal electrical components control); the hollowed-out tray is installed in the cabinet through the slideway, and is made of stainless steel and arranged in layers; the baffles around the tray are formed by welding stainless steel rods, and the bottom of the tray is a stainless steel screen, mesh The size can be adjusted according to the size of the seeds, but the mesh must be smaller than the size of the seeds to avoid accidental leakage of seeds from the upper tray to the lower tray and sample confusion.

Small sample tray: The sample tray can be round or square, and the bottom can be a hollow screen or a solid bottom. The material can be high temperature resistant hard plastic or glass. In actual work, it can be cultivated with a diameter of 9 cm. A dish or a 12 cm petri dish works well as a sample tray.

Motor fan: two sets of motor fans are installed on the top of the dryer, and the air is sent from the top to the main space, so that the air in the main space can circulate, the temperature is uniform, and the water vapor in the seeds is taken away at the same time;

Electric heating pipes: located on the left and right side walls and the rear wall of the cabinet. There are at least 3 sets of heating pipes on the upper, middle and lower parts of the side wall and rear wall to ensure rapid and uniform heating in the box;

Air outlet: the air outlet is located at the bottom of the box;

The temperature sensor and humidity sensor are installed at the bottom of the box close to the air outlet and above the tray in the middle of the cabinet. The temperature sensor senses the temperature in the main space, and the humidity sensor directly senses the moisture emitted by the seeds and the moisture contained in the wind near the outlet.

A method for drying vegetable seeds suitable for medium and small samples, comprising the steps of:

Put the sample seeds that need to be dried in a small sample tray with a label, then put them in a tray, and place them in the cabinet of the dryer. The temperature in the cabinet during the drying process is controlled at:

If the room temperature is lower than 30°C, start the hot air circulation to control the temperature in the space between 30°C and 32°C;

If the room temperature exceeds 30°C, start natural wind circulation, and use room temperature as the drying temperature;

The difference between the temperature measured by the two sets of temperature sensors in the middle of the cabinet and the air outlet controls the power of the fan, and the difference between the measured value of the temperature sensor and the temperature preset value controls the power of the electric heating tube;

The humidity sensor in the cabinet measures the moisture emitted from the surface of the seeds. If the humidity measurement is equal to or lower than 1%, the air circulation will automatically stop after 10 hours of continuous drying to ensure sufficient drying.

The beneficial effects of the utility model are: not limited by seasons and weather, the fast drying of fresh seeds can be realized, moldy deterioration can be effectively prevented, and drying time can be saved; the drying machine occupies a small space, but the amount of samples processed each time saves space. Since the seeds are fully dried and have less pathogenic bacteria, they are more suitable for cold storage or frozen storage to ensure the quality of the seeds during storage. When you need to sow, you can sow directly without worrying about the germination rate of the seeds. The drying machine provided by the utility model is especially suitable for rapid drying of medium and small sample seeds, especially vegetable seeds, by breeding units and scientific research institutes under the premise of ensuring the vitality of the seeds.

Take cucumber seeds as an example: the water content of the seeds after natural drying is generally 8-11%, and the water content of the seeds after drying with a dryer can reach 4%, which is greatly reduced; in terms of drying time, it takes 4 to 6 days to dry naturally. Humid summers and rainy days last longer. The drying time of the dryer only needs 24 to 36 hours (it takes a little longer in summer and rainy days with high humidity, and 36 hours is enough), which greatly shortens the drying time and can effectively prevent mildew and germination; the volume is 1 meter * 0.5 meters * The 1.5-meter dryer processes at least 400 individual seeds each time, and at least 10 3-meter-long bamboo poles need to be hung to dry the offspring of 400 individual plants, covering an area of about 30 square meters and requiring dry and ventilated environmental conditions , In continuous rainy days, it is inevitable that the seeds will become moldy and germinate. The use of the device and method is convenient, quick and efficient, and is not affected by weather conditions.

The temperature sensor 5 above the tray monitors the temperature at the sample. If it is lower than 30°C, the electric heating tube and hot air circulation will be activated to keep the temperature between 30°C and 32°C; if it is higher than 30°C, the controller will not start the electric heating tube. Only the natural wind circulation is activated. When the humidity sensor at the tray and the air outlet detects that the humidity reaches or is less than 1% and the difference between the values measured by the two sets of humidity sensors is 0, continue to dry for 10 hours to ensure that the seeds are fully dry. Tray 9, the hollowed-out tray is installed in the cabinet through the slideway, made of stainless steel, arranged in layers, the baffles around the tray are welded by stainless steel rods, the bottom of the tray is a stainless steel screen, the mesh size It can be adjusted according to the size of the seeds, but the mesh must be smaller than the size of the seeds to avoid accidental leakage of the seeds in the upper tray to the lower tray and sample confusion.
