Pasteurization Line

Details

Description

 

*This machine is not certified by ETL/UL/NSF rules.
*Please check the laws in your country about food preparation before finish your purchase.

 

PROCESS

Prepares and heats all ingredients up to 80ºC in the process tank (preparation and heating time: 50 min.).

Activates the pump in order to transfer the mixture into the transfer tank.

Begins preparing a new mixture in the process tank.

Connects the cooling tower and the cooling water reservoir.

Activates the circulating pump to force the mixture through the homogenizer.

When leaving the homogenizer, the mixture circulates through the heat exchanger, dropping the temperature from 80ºC to 4ºC, then conducts the pasteurized mixture to a maturation vat (refrigeration time to 4ºC: 60 min).

After the cooling is concluded, the process restarts by loading the new mixture, which has already been prepared in the process tank, into the transfer tank (this cycle is continuosly repeated).

The maturation vat is connected to a continuous freezer through a non-toxic hose.

The continuous freezer (SUPER C, SUPER C PLUS, SUPER C3 or C-JET) has a special pump that suctions the mixture from the maturation vat and produces the ice cream. Finamac continuous freezers allow enough outlet ice cream pressure to supply automatic filling machines to fill cups, sundaes, cones, etc.

Has the optional capability to connect the continuous freezer to a Finamac Fruit Feeder to introduce pulps and solid ingredients into the ice cream.

*Production depends on the climatic conditions of the location where the machine is installed.

LINE FILTER

PURPOSE: To retain impurities and particles not dissolved in the mixer tank.

Constructive material: AISI 304 stainless steel.

Dismountable.

Connects to the process with tri-clamp connections.

 
HEAT EXCHANGER

PURPOSE: To cool the homogenized mixture, completing the pasteurization cycle.

This cooling occurs by turbulent flowing through the lines formed between the plates, in thin threads that are a millimeter thick. On one side of the plates the product circulates to be cooled; on the other side, counterclockwise, the cooling fluid flows in two stages: First, it cools the mixture from 80ºC to 40°C with water derived from the hydraulic circuit of the cooling tower; second, it cools down from 40°C to 4ºC with a 30% water and alcohol solution. Outlet temperature of mixture: + 4ºC. Solution temperature derived from the cooling unit: + 2ºC.

DESCRIPTION:

Counter-flow heat exchanger uses AISI 316 stainless steel plates, insulated with dismountable nitrile rubber joints.

Capacity: 300/600/1200 liters/h (mix with 38% solids).

Double passage circuit:

First Stage: Cools the incoming mixture at 80ºC to 32ºC, due to thermal exchange with 1800 l/h of water from the cooling tower, incoming at 28.0ºC and out at 35.1ºC, pressure drops on the mixture side of 5.0 mCA, and on the tower water side at 0.5 mCA. Amount of heat exchanged: 12672 kcal/h.

Second Stage: Cools the incoming mixture from 32.0ºC to 4.0ºC, due to thermal exchange with 1500 l/h of cooled water/alcohol solution, incoming at 2.0ºC and out at 7.0ºC, pressure drops on the mixture side of 7.5 mCA, and on the cooled water side at 0.5 mCA. Amount of heat exchanged: 7392 kcal/h.
