AS 1187:1996 pdf download.Farm milk cooling and storage systems.

(b) Holding The temperature of the milk after cooling shall not exceed 4°C. This holding temperature shall be maintained by the

operation of the cooling and agitating equipment or by the insulating properties of the tank, or by both.

(c) bisuhiring efficiency The thermal insulation of the tank shall be such that at an ambient temperature of 35°C the rate of rise of the mean temperature of the milk. initially at 4°C. shall not exceed 1°C in 4 h when the vessel is filled to the maximum rated volume and the milk allowed to stand without further cooling.

1.6.4 In an ambient temperature of 40C The milk cooling and storage system shall operate for at least 2 h in an ambient temperature of 40°C without interruption, by protective devices and without overheating of the motors.

1.7 AGI1ATOR PF:RFoRMANCI

1.7.1 (;eneral The tank shall he fitted with means for mechanical agitation of the milk in order to meet the cooling performance,

as listed in Clause 1.6, and to mix the milk without causing overflow.

1.7.2 Cooling cycle During the cooling cycle the agitation system shall he set to start automatically and operate continuously

(see Clause 2.5.6.4).

1.7.3 Non-cooling cycle During the non-cooling cycle the agitation system shall be set to operate intermittently br periods of at

least 2 mm. at intervals of not greater than mm (see Clause 2.5.6.4).
