A heating, ventilation and air conditioning (HVAC) system includes a condenser to condense a flow of refrigerant into a liquid state. The system further includes an economizer assembly having at least one separator chamber to separate liquid refrigerant from vapor refrigerant. The economizer assembly shares an upper common wall with at least a portion of the condenser and the flow of refrigerant from the condenser into the economizer assembly proceeds through a flow opening in the upper common wall. A falling film evaporator exchanges thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.

A bulk fluid monitoring system and method for monitoring milk is provided, including a plurality of sensors for providing information in relation to properties of a bulk fluid, a memory for holding data parameters including information provided by the sensors and a predetermined time-and-temperature curve for a fluid, a processor for determining whether the information in relation to properties of the bulk fluid is within the bounds of the time and temperature curve for a fluid.

Methods, compositions, and articles of manufacture for preparing frozen beverages are described. The methods and articles generally include first and/or second frozen pellets. Upon mixing the frozen pellets with an appropriate liquid for a sufficient time, a frozen beverage is obtained. Articles of manufacture including frozen pellets, as well as optional objects such as straws, spoons, and mixing containers are disclosed. Methods, compositions, and articles of manufacture for preparing frozen pellets are also described.

A machine for producing and dispensing products such as ice cream, iced beverages or granita comprises a removable product-containing tank which is provided at its front end with a tap for dispensing the product and which, via its rear opening, sealingly houses a cooling element with a substantially horizontal axis and a motor-driven mixer element. The tank is removable from the machine by means of extraction from its operating position in a disassembly direction which is substantially parallel to the axis of the cooling element, and snap-engaging means for locking the movement of the tank are provided between the tank and its seat on the base of the machine, said means being able to be manually released by means of operation of at least one operating lever.

A method for preparation of human milk to be stored includes the steps of subjecting the human milk (M) to a treatment for inactivating or reducing an amount of biological contaminants in the human milk, freezing the human milk and forming flakes of the human milk, and collecting the frozen human milk flakes (F) in a container. This method and an according apparatus enable storing human milk for later use in a very small dose, i.e. in the form of pasteurized frozen milk flakes.

The method of the invention is characterized in that in the first phase the device installation is filled with processed liquid product, yielding a low pressure zone and then the processed liquid product is introduced under high pressure into the cavitation process, where moving at a rate of not less than 3 m/s and under pressure of not less than 20 bar is introduced to the cavitation and rotation location of the separated streams of the processed liquid product, which rotating in the further part, in the longitudinal axis of the cavitator, move in the opposite directions, resulting in differential pressure leading to cavitation process with effects characteristic for sterilization and homogenization with heterogeneous parameters, wherein in the next phase a separation takes place into a liquid product, which has a particle size larger than 600 nm and a liquid product which has a particle size smaller than 600 nm, wherein the liquid product of larger particle size is directed to cooling and complementary cavitation reprocessing, and the liquid product of smaller particle size is subjected to particle size analysis control, by which the liquid product, which meets the preset parameters, is directed to the finished product acceptance, and the liquid product which does not meet the acceptance criteria is sent to the next reprocessing.
