Q

Is a chilling method

that is periodically sprayed on the
carcasses combined with an air velocity of 1.5 to 3 feet/second for up to 10 hours.

take note: it uses cold water 34°F to 41°F (1°C to 5°C)

Q

this is a chilling method

that is an atypical chilling procedure, due to its deviation from the “10/10 rule of thumb”. Typically defined as a chilling procedure where the muscle is chilled to -1 °C by 5 hour post mortem.

14
Q

can be defined as a procedure whereby carcasses are chilled for
varying periods (always more than two stages) at different chilling temperatures. It’s mainly based on the principle of the first chilling the carcasses
rapidly until the ideal principle of rigor mortes is completed

16
Q

The primary chilling is completed when the warmest point of the carcass come to a temperature of about ?? With current
technology, these temperatures can be reached in small carcasses in 16-24 hours and in large carcasses in less than 36 hours.

A

7°C - for meat
3°C for the offal

17
Q

Primary cooling can be done in ________ or ________. In cold rooms, this process occurs in two or three phases:

A
  1. small cold rooms
  2. cooling tunnels
18
Q

In this phase of primary chilling

the air temperature is kept at around 0°C. Air movement is maximized to cool the carcasses efficiently.
Care must be taken to prevent superficial freezing.

19
Q

in this phase of primary chilling

For large carcasses only after 10-12 hours, air circulation is reduced while maintaining the same temperature and humidity.

this phase lasts about 6 to 10 hours

20
Q

in this phase of primary chilling

The carcasses are transferred to cold storage, where their temperature stabilizes.

21
Q

are usually liquids, and are used to transfer heat from the substance being cooled to a heat exchanger where the heat is absorbed by a primary
refrigerant.

air conditioning act as secondary refrigerant

A

Secondary refrigerants

22
Q

what is the simplest secondary refrigerant that is much used in air conditioning work above 0°C.

23
Q

In secondary refrigerant for low temperature application it uses?

A
  1. brine
  2. glycol
  3. oils
24
Q

For secondary refrigerants for high temperature apllication it uses

A

air conditioning

is an important part of the distribution and logistics process as it keeps the product in the **correct**, **safe**, and **high-quality state** in which it was initially shipped. It ensures that the product reaches the end consumer at the highest possible quality, without any potential for harmful bacteria to grow.
