Hoyer KF 3000 XC Hoyer KF 3000 N and XC Continuous Ice Cream Freezers Application through the cylinder the air is whipped into the mix by a dasher. Refrigerant surrounding the cylinder supplies Freezing and whipping of ice cream mix and air to the freezing. Stainless steel blades scrape the frozen ice produce ice cream. Scraped surface freezing of other cream from the inside wall of the cylinder, and a second products. gear pump forwards the ice to a filling machine. Operating Principle Standard Design The ice cream mix is metered into the freezing cylinder The Hoyer KF 3000 Freezers comply with the 3-A by a gear pump. A constant airflow is fed into the sanitary standards of the Food & Dairy Industries cylinder together with the mix. During the passage Supply Association, USA.

The frame, sheeting and refrigeration system are Mix and ice cream pumps are gear pumps. The pumps constructed from stainless steel. All parts coming into can be adjusted to compensate for normal wear. The contact with the ice cream are manufactured from design and the materials are carefully chosen to stainless materials. minimise wear. Installation. The freezer units are ready to be Instant stop allows a temporary stop in production with connected to power, refrigerant, air and mix supply. minimal loss of ice cream and change in the ice cream The freezing cylinder is made of pure nickel and the quality. inside surface is hard chromium plated and mirror finished. The refrigeration system ensures a stabile cooling Nominal Output which is essential to keep correct viscosity or 3000 litres per hour (793 US gallons). temperature of the ice cream. Hot gas is used to prevent The output capacity is based on the following freezing up during production and if necessary during conditions: stop periods, e.g. in connection with instant stop. The Inlet of mix +5°C (+41°F) liquid NH3 supply must be vapour-free and have a minimum absolute pressure of 4 bars (58 psi). The Outlet of ice cream –5°C (+23°F) suction pressure at the Hoyer KF-freezer should be Suction temperature –34°C (–29°F) corresponding to –34°C (–29°F). Oil content in ammonia max. 30 p.p.m. Drive. Power is transferred from the main motor directly Overrun 100% to the dasher by V-belts. Mix type: Normal ice cream mix containing 38% total solids. Upon receipt of actual mix recipe the precise capacity/outlet temperature can be determined. Hoyer KF 3000 N Standard Design. In addition to the already mentioned standard design, the Hoyer KF 3000 N also includes the below mentioned: Compressed air is required for control of overrun and CIP pumps (if CIP pumps are applied). Control panel. All functions of the machine are operated from the front panel which includes a meter for motor load, air-pressure gauge, start and stop push buttons for pumps and main motor as well as a handle for refrigerant and mix flow control. Pump drive. A speed variator drives the inlet and outlet pumps. The capacity can be set from 20 to 100%. Mix pump capacity: 320-1600 litres per hour (85-423 US gallons). Standard accessories include a set of tools, sprockets to changing the cylinder pressure and a pulley for reducing dasher speed.

Optional Equipment Hoyer KF 3000 XC for the Hoyer KF 3000 N Standard Design. In addition to the standard design already mentioned, the KF 3000 XC also includes the CIP-Pump (Cleaning-In-Place). All parts of the freezer below mentioned: coming into contact with the product are cleaned without dismantling. When activating CIP from the control panel the pumps disengage and thereby allow a strong flow of detergent. Pumps and dasher are automatically started at certain intervals during the cleaning process. Three-way cock valve with fittings for ice cream outlet piping. Flavour feeding pump. Proportional feeding of liquid flavouring and colouring additives without solid particles directly into the freezing cylinder Stop valves for refrigerant.

All functions of the machine are operated from the panel. Refrigeration, air and mix flows are controlled Continuos aerator (Separate unit). according to computer calculations based on the Set of spares. For 3000 or 6000 hours. operator’s pre-selected values for ice cream viscosity or temperature, overrun and capacity. The control panel provides clear and easily understood information to the operator by means of graphic displays and written text. Full production data for up to 100 products can be stored in the computer memory, facilitating start-up and enabling optimum production conditions to be attained quickly. Essential production data (e.g. Ice cream flow, viscosity and overrun) are displayed constantly during production and at the touch of a button the operator is able to bring other data to the screen, e.g. mix and ice cream temperature, accumulated mix and ice cream flow, pump speed etc. Production values can be altered both before and during production. A manual operation mode is available if desired. If disturbances occur during production, these will be indicated on screen so that action can be taken. In the case of serious disturbances the instant stop procedure will automatically be activated. A service screen occurs automatically according to pre-set hours of production. The screen provides easy access to necessary information for service and
