Abstract: The present invention relates to filters for coffee, tea, hot chocolate etc., in which a filter is placed in a cylindrical container and whatever is to be filtered is placed in the filter that has been placed in the cylindrical container. Thereafter, either hot or ice cold water, in the case of iced tea, is poured into the cylindrical container over that which is to be filtered. In more cases than not, the filter collapses, especially in the case of coffee and tea, the result is that coffee grinds and tea leaves eventually get into the coffee cup or tea leaves get into the tea cup. The present invention solves this problem by providing a retention ring of shape retaining inert material, such as plastic or stainless steel that is capable of being compressed in size placing it inside the filter that has been placed in the cylindrical container that is to be filled with a product.

Abstract: An apparatus for filtering and cooling liquid, with four filtration chambers are connected by a series of passageways. The apparatus is mounted on a cart so that it may be rolled into position under a machine quickly and easily. Once the apparatus is in position, the machine is drained of its debris-laden oil which flows directly into the first chamber and through the first wire mesh filter. The liquid is then forced either by gravity or by pressure through the remaining chambers and their respective filters which have progressively smaller pore sizes. The tortuous movement of the liquid around the weirs helps to cool the liquid while the filters remove foreign particles from the liquid. Once the liquid reaches the fourth chamber, a pump is used to pump the cleansed liquid back into the machine so that it may be reused. The inlet to the pump may be fitted with an optional fifth filter element.
