  • Publication number: 20200256604
    Abstract: Provided is a means for easily producing a plurality of types of flake ice each having a different freezing point and approximately uniform solute concentration. There is provides a flake ice production device. A drum includes an inner cylinder, an outer cylinder surrounding the inner cylinder, and a clearance formed between the inner cylinder and the outer cylinder. A refrigerant supply unit supplies a refrigerant to the clearance. A rotary shaft rotates taking a central axis of the drum as an axis. An injection unit rotates together with the rotary shaft and sprays brine toward the inner peripheral surface of the inner cylinder. A scraping unit scrapes off flake ice that is generated as a result of brine having been sprayed from the injection unit becoming attached to the inner peripheral surface of the inner cylinder, which has been cooled by the refrigerant supplied to the clearance.

  • Publication number: 20180340721
    Abstract: Provided is a means for more efficiently generating ice which has a high cooling capacity. A flake ice production device generates ice by cooling the wall surface of an inner cylinder and freezing brine that has adhered to the wall surface of the cooled inner cylinder. A spraying unit supplies brine to the wall surface of the inner cylinder by causing the brine to adhere thereto. A stripping unit collects the ice generated on the wall surface of the inner cylinder. In addition, the flake ice production device is designed such that formula (1) is satisfied when Y represents an ice making speed indicating the amount of ice generated on the wall surface of the inner cylinder per unit time, and x1 represents the thermal conductance rate of the wall surface of the inner cylinder. Formula (1): Y=f(x1).

  • Patent number: 10085461
    Abstract: The present invention not only forms an electric field environment that can be controlled to differentiate between preservation of food freshness and promotion of ripening but also promotes fermentation by fermentative microbes, propagates plankton and inhibits bacterial reproduction. An electrode plate 2 is set inside a refrigerator 1 or an adjustable temperature box 6. Food 3 or a yogurt container 9 is place thereon. The electrode plate 2, 10 is connected to a power source 4, 11. Selection between food freshness preservation and promotion of ripening, and promotion of fermentation of fermented foods such as yogurt are performed by rectification, and voltage and frequency control of the power source. Additionally, propagation of phytoplankton and inhibition of bacterial reproduction are performed by controlling the frequency, voltage and ON/OFF timing of the power source.
