PEMAKAIAN ALAT RETORT PADA KEMASAN MAKANAN BASAH, MAKANAN BASAH BAKAL AWET - PART 2

Summary

This video provides a step-by-step demonstration of using a retort machine to preserve food, specifically empek-empek, through sterilization. The presenter explains the function of key components like the temperature and pressure indicators, safety valves, and gas usage for the retort process. It covers the preparation, including filling the retort with water, heating, loading the products, and setting the correct temperature and pressure to ensure proper sterilization. The video also touches on the cost efficiency, with detailed calculations on gas usage and packaging costs. The end goal is to showcase how this process helps in expanding the product's shelf life and distribution without compromising its quality.

Takeaways

• 😀 Introduction to the process of using a retort machine to preserve food.
• 😀 The retort machine includes indicators for temperature and pressure, crucial for safe operation.
• 😀 The temperature must reach 121°C to kill pathogens and ensure the food is properly preserved.
• 😀 The pressure should reach a maximum of 1 bar, after which the machine will automatically release excess steam.
• 😀 To start, fill the retort with water, ensuring it is below the basket level before closing it securely.
• 😀 The cost to retort a single package of food (e.g., empek-empek) is very low, around IDR 150 per package.
• 😀 Gas consumption for the retort process is minimal, with a 3 kg LPG gas cylinder allowing for 135 retort packages.
• 😀 The products being retorted are packaged in aluminum foil bags designed for retorting, which can be found online.
• 😀 Proper loading of the retort machine is essential to prevent overpressure and damage to the packaging.
• 😀 After the retorting process, it is crucial to allow the steam to dissipate before opening the machine to avoid burns or accidents.

Q & A

What is the purpose of the machine demonstrated in the video?

The machine demonstrated in the video is used for sterilizing food products, specifically empek-empek, by applying heat and pressure to kill pathogens and bacteria to prolong shelf life.

How does the temperature indicator on the machine work?

The temperature indicator shows the current temperature of the machine, and the target temperature for sterilization is 121°C. Once this temperature is reached, the machine can kill bacteria and pathogens effectively.

What happens if the pressure gauge reaches 1 bar?

When the pressure gauge reaches 1 bar, the machine's safety valve activates and automatically releases excess steam or pressure to prevent overpressure.

How much does it cost to sterilize one package of empek-empek?

The cost to sterilize one package of empek-empek is approximately 150 IDR, considering the use of LPG gas and the sterilization process.

What is the maximum capacity for each batch in the sterilizer?

Each batch can sterilize up to 45 packages, with three racks in the sterilizer, each holding 15 packages.

Why is it important not to overfill the sterilizer racks?

Overfilling the racks may cause the plastic packaging to burst due to the high pressure inside the sterilizer, leading to product spoilage and failure of the sterilization process.

How long does it take for the machine to reach the required sterilization temperature of 121°C?

It takes approximately 17 minutes for the machine to reach the required temperature of 121°C for sterilization.

How long should the products be held at 121°C for effective sterilization?

The products should be held at 121°C for about 7 minutes to ensure that bacteria and pathogens are effectively killed.

What should be done after sterilization to release the pressure inside the machine?

After sterilization, the pressure inside the machine is released by slowly opening the valve to let out the steam. This process can take around 30-35 minutes until the pressure indicator shows zero.

What happens to the plastic packaging after the sterilization process is complete?

Once the sterilization process is complete and the pressure is released, the plastic packaging will deflate as it cools down, returning to a flat shape.
