It states swirl nozzle and is arranged in the ice-making compartment front central and circumferential direction, the hollow pipe, institute is arranged in the ice-making compartment tail portion
Stating is the hollow circulation nozzle outside hollow pipe, and hollow circulation nozzle tail portion is the mixing chamber, the mixing chamber tail
Portion is ice pellets outlet, and outside is surrounded by the pre-cooling chamber, the tail portion and front of the pre-cooling chamber be respectively equipped with high pressure gas into
Mouth and outlet, the pre-cooling is intracavitary to be equipped with the eddy flow partition, and high pressure gas flows successively through the pre-cooling chamber and the low temperature system
Cold is respectively led into the swirl nozzle and the hollow circulation nozzle, is provided with valve in each pipeline, changes the atomization
The structural parameters of nozzle and the swirl nozzle can change the ice pellets parameter of generation.
Water generates water droplet by atomizer atomization, and high pressure gas is pre-chilled through the pre-cooling chamber to cool down, and recycles cooling capacity,
Low-temperature airflow heat loss is reduced and eliminates, energy saving, the eddy flow partition plays a supporting role and strengthens flowing and heat transfer, in advance
Low-temperature airflow after cold is reduced to setting low temperature through the Cryo Refrigerator, is divided into two flow paths, a flow path is through the swirl nozzle
Directly mix and freeze to generate immediately ice pellets with water droplets eddy flow in the ice-making compartment, the ice pellets air-flow of generation passes through hollow
Pipe, another flow path mixes through the hollow circulation nozzle with the ice pellets air-flow of generation, due to the injection of the hollow circulation nozzle,
Volume is inhaled and blending effect, ice pellets further freeze to be formed in the mixing chamber, and the ice pellets continuously generated is exported by ice pellets and drawn,
It controls the Cryo Refrigerator and the valve changes the temperature of low-temperature airflow and the generation pressure of flow and change water droplets
Power and flow, granularity, temperature and the flow of ice pellets capable of on-line.
The high pressure gas is provided by compressor having internally mounted offer or by external high pressure gas source.
The Cryo Refrigerator is mediate contact cryogenic refrigerating unit or directly contacts refrigerating plant.
The beneficial effects of the invention are as follows continuously ice pellets is produced, can prepare at any time without interruption；The partial size of ice pellets and temperature etc.
Parameter can on-line control and change；Swirl nozzle eddy flow mixed is strong, guarantees ice pellets formation speed；The contact of hollow circulation nozzle
Area is big, and volume is inhaled, blending and ejector action are strong, guarantees ice pellets sizing；Low-temperature airflow directly connects with the highest water droplets of temperature
Touching guarantees heat-transfer intensity, greatly improves freezing speed, water droplets is made to generate ice pellets in time；Low-temperature airflow directly with temperature most
The low ice pellets contact tentatively generated, guarantees the heat transfer driving temperature difference, the ice pellets tentatively generated can be made further to cool down sizing, and beat
Dissipating prevents adhesion；Outside setting fore-cooling room, can eliminate and reduce heat loss, high pressure gas pre-cooling cooling, energy saving, and eddy flow
Partition makes high pressure gas that the reverse eddy flow flowing of intracavitary formation, augmentation of heat transfer be pre-chilled.System structure is simple, small in size, light-weight,
Low manufacture cost can be used for continuously producing ice pellets, such as jet of ice grains in surface clean, derusting and ice storage and food processing
Equal applications.
