Sterilized and packaged mineral water comprises sterilized mineral water having a hardness of not less than 50 mg/l and a content of dissolved carbonic acid gas ranging from 9 to 30 mg/l (as calcium carbonate) and a number of bacteria of not more than 10.sup.-3 /ml which is obtained by sterilizing pumped-up mineral water having a hardness of not less than 50 mg/l and a content of dissolved carbonic acid gas ranging from 10 to 31 mg/l by filtering through a filter having a pore size of not more than 0.22 .mu.m. The packaged and sterilized mineral water can be effectively prepared by a method which comprises packaging pumped-up mineral water in a container without subjecting it to any heat-sterilization treatment wherein the mineral water is sterilized by passing through a filter having a pore size of not more than 0.22 .mu.m, packaged in a sterilized container under an aseptic condition of not more than Class 100 and then the container is airtight-sealed. Thus, packaged and sterilized mineral water having excellent keeping quality can be obtained without subjecting pumped-up mineral water to any sterilization by heating and without using any antibacterial agent and it has a high hardness and a high carbon dioxide content as well as good taste peculiar to the original mineral water.

A method for feeding a solid-liquid mixture comprised of a liquid and a solid having a specific gravity greater than that of the liquid comprising depositing the solid component around a feed opening disposed at the bottom of a mixing container and feeding the solid-liquid mixture to a container for packing the same through the opening is provided and the method can effectively be carried out utilizing an apparatus comprising a mixing container, a feed opening disposed at the bottom of the mixing container, a feed controlling device disposed below or within the feed opening and characterized in that it comprises a collecting device for depositing the solid component of the mixture around the feed opening. The present invention makes it possible to feed the solid-liquid mixture in a desired constant mixing ratio since the ratio can easily be controlled by simply depositing solid component around the feed opening and changing the cross-section of the flow path at any position from the feed opening to the chute member.

An apparatus for producing sterile air comprises a sterilizing filter for filtering microbes in air and an air heater for heating the filtered air for its sterilization. There is provided means for disposing of the sterile air from the air heater at an initial stage of production of the sterile air.

Apparatus for producing sterile air

Two or more sets of liquid substance feed means are provided each which consists of a supply device, a transport pipe and a delivery pump. These feed means are connected through a valve to a single transport pipe and back pressure devices are provided in all but one of the liquid-substance feed means. While a liquid substance is being fed by one of the feeding means, another liquid substance having different properties is passing in the other feed means and using the back pressure device provided in the latter means, the flow rate and the pressure of the latter liquid substance are controlled as the same as those of the former being fed by the former feed means. Being switched over, in this condition, from the former feed means to the latter to feed the latter liquid substance, two or more kinds of liquid substance having different properties can be fed sequentially at predetermined pressure and flow rate.

System for feeding liquid substances

A filling apparatus for charging a liquid or highly viscous product into containers. The apparatus has a pressurizing tank, buffer tank, filling tank and a filling machine. The tanks have controllable pneumatic internal pressure. The product is fed at a high pressure from the pressurizing tank to the buffer tank and, after decreasing the pressure in the buffer tank, the product is transferred at the normal or low pressure from the buffer tank to the filling tank and filling machine.

Filling apparatus

A system having first, second and third pipes connected respectively to first, second and third ports of a three-way valve. A by-pass pipe is connected at its one end to one of the second and third ports after disconnecting the associated one of the second and third pipes therefrom and at the other end to the other of the second and third pipes prior to the cleaning operation of the system.
