Abstract: A preparation method for caffeine control and device thereof, mainly consisting of: a. mixing coffee powder and water in a container; b. applying a vibration force to the container for an acting time, and maintaining the operating temperature during this stage within a first working temperature range; c. compressing the space within the container to cause specific components in the coffee powder to be extracted and form coffee liquid; d. heating the coffee liquid obtained from step c to a second working temperature. Accordingly, vibration extraction and compression process at the first working temperature and the further heating process at the second working temperature are used to control the caffeine content of hot coffee.

Abstract: The present invention provides a super fractionating apparatus and process, consisting of a fractionation column having an adsorbent body that assists in the fractionation process, and further includes a carbon dioxide supply unit, a carbon dioxide flow pipe, a raw material supply unit and a raw material flow pipe. The carbon dioxide flow pipe connects to the carbon dioxide supply unit and the fractionating column, and a pressure unit and a temperature control unit are configured on the carbon dioxide flow pipe. The raw material flow pipe connects to the raw material supply unit and the fractionating column, and a pressure unit is configured on the raw material flow pipe. The fractionating column having the adsorbent body disposed therein causes turbulence in the fluid within the fractionating column, thereby increasing fractionation efficiency and assisting in stabilizing the extracts, which facilitates collection thereof.

Abstract: An automatic tea maker comprises a cover body, a tube base, and a bottom base, wherein the cover body is covered on the tube base, which is eccentrically disposed on the bottom base. A partition is disposed on an interior of the tube base to partition an independent drainage area. A vent disposed on the partition communicates with the tube base. Each of water exits, provided with a stopping members, are disposed on a base surface of the tube base. A baffle extends from an internal periphery of the bottom base with push rods placed on the baffle protruding outward from the water exits. The push rods placed on the baffle extend corresponding to the stopping members of the water exits, is able to push the stopping members away from the water exits, when the tube base is slanted corresponding to the bottom base.

Abstract: An automatic tea maker device with buoyancy structure including a teacup, a percolator cup, and a cap, wherein two tube members are configured within a receptacle of the percolator cup, and lower portions of the two tube members are interconnected with a passage there between. A float is configured within one of the tube members to actuate a limit flow rod penetrated within a through hole. A plug end of the limit flow rod seals a tea outlet of a filter seat. A pull rod having a plunger head is disposed within the other tube member. Tea within the percolator cup slowly seeps into one of the tube members through an interstice between the limit flow rod and the through hole, thereby causing the float to float upwards, thus opening the tea outlet allowing the ready steeped tea to flow into the teacup, thereby achieving objective of time setting.
