Abstract
A beverage extracting or brewing apparatus for vending machines includes a mixing ball for mixing water and raw material of a beverage, a cylinder having a spherical upper inner surface, a straight cylindrical communication path between the mixing ball and the cylinder having a flush inner surface, a valve opening and closing an inflow port of the cylinder and having a spherical upper surface, a valve shaft functioning as part of a pressurized air supply path into the cylinder, a filter positioned at the bottom of the cylinder and a pressurization device for supplying the pressurized air into the cylinder to forcibly filter the mixture liquid in the cylinder through the filter. The mixture liquid from the mixing ball can be sufficiently and efficiently mixed and stirred in the communication path and even in the cylinder, and smoothly flows into the cylinder through the space between the spherical inner surface of the cylinder and the spherical upper surface of the valve. The mixture liquid does not stick to various portions in the apparatus, thereby maintaining the apparatus sanitary. Since the mixture liquid is sufficiently and quickly mixed before being extracted, the processing time of the beverage of the vending machine is significantly reduced.
