Vacuum pneumatic system for conveyance of ice

Vacuum pneumatic conveying apparatus and method are described to provide for a simple, economical, convenient (and preferably automatic) system for conveying ice on an as-required basis from a source such as an ice maker to one or more receptors at locations remote from that source. The system can be configured such that dispensing locations can be added or eliminated from the system or temporarily taken "off line" from the system without the need to change the basic system configuration or the central ice providing apparatus. The apparatus in various embodiments includes an ice source, a conveying conduit from the source to the receptor, a vacuum pump for moving the ice through the conduit by vacuum, and the receptor to collect the conveyed ice. The receptor may be an ice/beverage dispenser, an accumulator for retention and discharge to further devices, an intermediate storage dispenser, or an air lock device from where the ice can be projected over significant distances. Ice and vacuum may simultaneously be routed into different branched routes, utilizing a unique diverter/air shifter with the capability of providing routing to up to four different routes. Appropriate sensors and controllers, which may be microprocessor-based, may be used to automate the system. The entire system is easily cleanable. The system is advantageously used by restaurants, groceries, hotels and motels, hospitals, laboratories, and many other establishments where the providing of ice at various locations is desirable or required.

Process and equipment for manufacturing clear, solid ice of spherical and other shapes

The process and equipment, according to this invention, for manufacturing clear, solid ice of spherical and other shapes are capable of making clear ice balls and block ice of other shapes in the mold quickly, efficiently, and with effective energy utilization. This process is characterized in the steps of:
    • a) preparing a mold for making ice balls and block ice of other shapes, which comprises an upper mold (24a) made of an insulating material and provided with a vertical injection hole (23) drilled therein and a water-injection nozzle (22) fitted in the hole; and a lower mold (24b) made of a water-freezing block (26) having coolant pipe (25) embedded therein;
    • b) preparing for a domed lid (21a) or the lid of a different shape made of an insulating sheet, said lid (21a) having a shape that fits in with the surface shaped for the upper mold (24a) and being provided with a cylinder for being fitted into the vertical injection hole (23); and a shaped hemispherical cup (21b) of the same insulating sheet, which similarly fits in with the shaped surface of the lower mold (24b);
    • c) assembling both halves of the mold (24) after the lid (21a) and the cup (21b) have been attached tightly to each other and placed in the mold;
    • d) then, keeping the liquid to be frozen cooled at a predetermined temperature and spraying the liquid intermittently in the direction of the water-freezing block (26) that has been cooled to a predetermined freezing temperature;
    • e) repeating the spraying operation to freeze the sprayed liquid in the container (21), layer by layer, until clear ice balls (20) or block ice of other shapes are formed; and
    • f) disassembling the halves of the mold under the ice-releasing effect, which the ice container (21) has on the ice-making mold (24), and immediately taking out We shaped ice balls (20) or the block ice of a different shape.


In the related art refrigerator, its structure for supplying water to a dispenser and water tank was complicated. In addition, since an icemaker is installed in a refrigerating chamber of the refrigerator, there is a problem in that the water supplied into the icemaker is frozen. Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator. According to an aspect of the present invention for solving the above problems, there is provided a refrigerator including a refrigerating chamber formed at a relatively upper portion of a refrigerator body and a freezing chamber formed at a relatively lower portion of the refrigerator body, which comprises an ice-making chamber which is partitioned in the refrigerating chamber by means of insulating walls and includes an icemaker for making ice and an ice storage for storing the ice made in the icemaker, a first heat exchanger for generating cold air to regulate the temperature in the ice-making chamber, and a second heat exchanger for generating cold air to regulate the temperature in the freezing and refrigerating chambers, wherein the first and second heat exchanger are components of a heat exchange cycle. According to the refrigerator of the present invention so configured, there are advantages in that the temperature in the refrigerating chamber can be accurately controlled, the loss of cold air can be minimized and the structures for supplying water into the icemaker and the dispenser can be simplified.
