Frunt-N1 Optional Equipment

Mix type: Normal ice cream mix containing 38% total solid. Upon receipt of actual mix recipe a definite capacity and outlet temperature can be determined.

Overrun                                          100

Oil content in ammonia                  <30PPM

Suction temperature                        -34 (-29)

Outlet ice cream temperature        -5 (23)

Inlet mix temperature                     +5 (+41)

1000Litre/hr (270 U.S. Gal) base on below condition:

Nominal Output

Standard accessories include a set of tools, a standard set of spares, sprockets for changing cylinder pressure and a pulley for min. dasher speed.

Mix pump capacity is from 80~550Litre/hr (21~145 U.S. Gal).

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 ammonia control. Pump speed is adjustable from 10~100%.

Compressed air from existing mains supply is required for control of the overrun and CIP pumps.

CIP (Clean-in-place). All parts getting contact with mix and ice cream are cleaned without dismantling. When activate the CIP program form the control panel, the outlet pump wheels and the inlet pump wheels disengage and allow for a heavy flow of detergent. Pumps and dasher are automatically activated at certain intervals during the cleaning process.

Instant stop allows a temporary stop in production with minimal loss of mix and change in the ice cream quality.

Mix and ice cream pumps are gear pumps, adjustable for endwise clearance to compensate for normal wear. The interior of the stainless steel housing is chromium plated to minimize such wear.

Drive. Power is transferred from the main motor directly to the dasher by V-belts.

Refrigeration system supplies constant cooling capacity to ensure the stable ice cream temperature and viscosity. During stop periods and whenever refrigeration is shut-off i.e. in connection with instant stop, hot gas is applied to prevent freeze-up. Liquid ammonia supply must be vapor-free and has a minimum absolute pressure of 4 bars (58psi) and the suction temperature should be -34 (-29).

The freezing cylinder is made of pure nickel and the inside surface is hard chromium plated and mirror finished. The dasher, equipped with scraper blades and a beater, is made of stainless steel.

Installation. The freezers directly are self-contained units ready to be connected to electrical power, refrigerant, compressed air and mix supply.

Frunt-N1 continuous freezers meet the 3-A sanitary standards symbol of the Foods & Dairy Industry Supply Association, USA. The freezer cabinet and refrigeration system are made of stainless steel. All parts contacting the mix and ice cream are made of stainless steel.

Standard Design

The ice cream mix is metered into the freezing cylinder by a gear pump. A constant air flow is fed into the cylinder with the mix. During the passage through the cylinder the air is whipped into the mix by a dasher. Liquid ammonia evaporating in the cooling jacket surrounding the cylinder supplies the freezing. Stainless steel blades scrap the frozen ice cream from the inside wall of the cylinder, and a second gear pump forwards the ice cream from the outlet end of the freezing cylinder to a filling machine.

Operating Principle

Freezing, mixing and whipping of ice cream and air to ice cream. Scrapped surface freezing of other products.

Application

Ammonia ice cream freezer, capacity 1, 000L / HR with 100% overrun
