HTST Pasteurization in Ice Cream

What Is HTST

HTST pasteurization helps make ice cream mix safe and fresh. HTST means High-Temperature Short-Time. The mix gets heated to at least 161° F for 15 seconds. This is called flash pasteurization because it happens fast. The main goal is to remove harmful bacteria and spoilage organisms. The mix keeps its flavor and texture.

You can look at the table to see how HTST is different from other methods:

HTST pasteurization uses special heat exchangers. This saves energy and keeps the mix the same every time. Most modern ice cream plants use this method.

Why HTST Is Used

HTST pasteurization gives you many good things:

• It destroys harmful bacteria and lowers spoilage organisms. This makes ice cream safe for everyone.

• It helps ice cream last longer. Your product stays fresh for more days.

• It keeps quality high. Quick heating and cooling stop changes in taste and texture.

• It is very efficient. The process uses less energy and works faster than old methods.

Scientists have proved HTST pasteurization works well. It kills germs and makes shelf life longer (Juffs and Deeth, 2007). HTST stops unwanted changes because it inactivates enzymes quickly (Ohlsson & Bengtsson, 2002). Most ice cream factories use HTST because it fits different production needs (Jo et al., 2018; Ranieri et al., 2009).

HTST pasteurization helps you make ice cream that is safe, tasty, and easy to produce.

HTST Ice Cream Mixing Plant Process

You can follow simple steps in an htst ice cream mixing plant. Each step helps you make safe and good ice cream mix. The plant uses new machines to keep things fast and the same every time.

Ingredient Preparation

First, you get the ingredients ready. You mix milk, sugar, and stabilizers in a steel tank. Mixing happens fast and spreads everything out evenly. You heat the mix to 55°C with hot water around the tank. This helps the ingredients melt and makes the mix smooth. Next, you heat the mix more to 75°C using hot mix that is already pasteurized. This saves energy and gets the mix ready for the next step.

Tip: Mixing fast and heating early stops lumps and makes the mix even.

Heating and Pasteurization

Now you move the mix to the heating and pasteurization step. The plant uses a plate heat exchanger to heat the mix to 85°C for 30 seconds. This kills bad bacteria and keeps the mix safe. The heat exchanger is very important. It heats the mix quickly and cools it down fast too. You get safe ice cream mix without losing taste or texture.

Pasteurization is the most important part. You must reach the right heat and hold it for the right time. The HTST pasteurizer makes this easy. You can trust the machine to keep your mix safe every time.

Homogenization and Cooling

Next, you homogenize the mix with high pressure. This step makes the ice cream smooth and creamy. The homogenizer takes out air bubbles and mixes everything well. You cool the pasteurized mix to 4-6°C before you store it. The plate heat exchanger helps cool the mix. It keeps the mix good and stops bad changes.

Note: Homogenization makes the ice cream creamy and stops it from separating.

Final Storage

You put the finished mix in a balance holding tank. The mix stays cold until you need it. The plant uses clean pipes to connect all the parts. You can watch the whole process on the control panel. The duplex tube filter takes out anything dirty before storage. You always get a clean and safe mix.

• Duplex tube filter

• Control panel for the whole machine

• Steel base with feet you can adjust

• Heating system with electric, gas, or steam boilers

• Two mixing tanks for making and heating the ice cream mix

• Balance holding tank

• Homogenizer

• Plate heat exchanger with 5 parts

• Clean pipes to connect each part

You can see how the htst ice cream mixing plant uses a nonstop process to work better. The process keeps your ice cream mix safe, saves energy, and gives you the same results every time.

Main Components of HTST Ice Cream Mixing Plant

Mixing Tanks

You begin with mixing tanks. These tanks mix things like milk, sugar, and stabilizers. They are made from strong stainless steel called 304 or 316L. This steel lasts a long time and is very clean. You can change the feet so the tank stands straight on any floor. The tanks can hold small or big batches. You can make between 500 and 10,000 liters each hour.

Tip: Stainless steel tanks help keep your mix safe and clean.

Duplex Tube Filter

The duplex tube filter takes out things you do not want in your mix. This makes your ice cream mix smoother and cleaner. The filter works before pasteurization. Only clean mix goes to the next step. You can switch filters without stopping the machine. This saves you time.
