Patent number: 10617779Abstract: The invention relates to a vacuum exhaust system of a sterilizer, comprising: a sterilization chamber; a first vacuum pump connected to one side of the sterilization chamber; an oil mist trap section for exhausting steam incoming from the sterilization chamber via the first vacuum pump; and a second vacuum pump connected to the first vacuum pump and the oil mist trap section. The vacuum exhaust system of a sterilizer according to the invention comprises the second vacuum pump connected to the first vacuum pump and the oil mist trap section, wherein by turning the second vacuum pump on to apply a vacuum to the operating oil in the first vacuum pump, thereby providing a certain pressure for evaporating water in liquid state to the first vacuum pump, the invention can vaporize the water vapor trapped in the operating oil in the first vacuum pump.Type: GrantFiled: January 25, 2019Date of Patent: April 14, 2020Assignee: CMTECH CO. LTD.Inventors: Heung Sik Min, Young Keun Ahn, Sung Jin Yang, Jin Woo Min

Patent number: 10448663Abstract: The present invention relates to a coffee roaster having a housing, a supporting plate located within the housing, a drum chamber located at one side of the supporting plate within the housing, a first support for supporting the drum chamber, and a second support for supporting the drum chamber. The supporting plate may include a heater. The first support may be adjacent to the outer circumferential surface of the drum chamber. The second support may be adjacent to the outer circumferential surface of the drum chamber and be spaced apart from the first support by a predetermined distance. As the drum chamber rotates by receiving a driving force for rotation from the first supporting unit, the drum chamber can be rotated without being obstructed by the heater.Type: GrantFiled: April 4, 2014Date of Patent: October 22, 2019Assignee: CMTECH CO., LTD.Inventors: Heung Sik Min, Young Keun Ahn, Sung Jin Yang, Jin Woo Min

Publication number: 20180264153Abstract: The present invention relates to a sterilizer using a hydrogen peroxide solution as a disinfectant, which includes: a disinfectant lifting and lowering unit capable of housing and transporting a disinfectant container filled with disinfectant; a sting unit which opens the disinfectant container; and a drain unit which drains discharging disinfectant from the disinfectant container, wherein the disinfectant lifting and lowering unit and the stinger unit are lifted and lowered along a transport guide provided in the housing. Since it is possible to supply hydrogen peroxide to the sterilizer without frequent replacement of the hydrogen peroxide container as disinfectant many times, there is an effect that sterilization of the sterilizer can be quickly performed.Type: ApplicationFiled: January 28, 2016Publication date: September 20, 2018Inventors: Heung Sik MIN, Young Keun AHN, Sung Jin YANG, Jin Woo MIN
