Production process of dried persimmon
Dried persimmons are produced according to the following basic steps:
Step 1: Select and classify fresh persimmons as raw materials for production
To produce dried persimmon products with delicious flavor and flexibility, you need to choose raw materials that ensure origin and quality. On the market today there are many different types of persimmons. If we do not choose the right type of persimmon suitable for drying, it will lead to dry, hard, not soft persimmons and lose the natural delicious taste of persimmons. O'Petit House's dried persimmon is selected from the Tam Hai persimmon variety or commonly known as bronze square persimmon, while the wind-hanging persimmon is made from fire egg persimmon. Tam Hai persimmons must be evenly ripened on the tree and will be carefully harvested for the drying process. The persimmons used for drying must be cooked evenly so that the persimmons are soft and flexible without drying out.
After harvesting persimmons, it is difficult to be uniform in size and ripeness. Therefore, before drying, it is necessary to classify persimmons to create uniformity in the ingredients, helping to ensure the delicious flavor of dried persimmons. Be sure to remove persimmons that are pest-ridden, crushed, damaged, etc. that do not meet the requirements.
Step 2: Wash persimmons after harvesting
After being harvested, fresh persimmons need to be washed thoroughly before drying to remove impurities such as sand, dirt, harmful microorganisms or pesticide residues remaining on the surface of the persimmon skin. .
Make sure to wash all persimmons before drying to ensure health safety for users. Be careful during washing to avoid using too much force, causing crushing and damage to the persimmon. To have smooth, supple dried persimmons, O'Petit House's drying technicians must dry them twice:
First time: Dry in a hot air dryer for just enough time
Second time: drying with charcoal over low heat to make the persimmon piece not only aesthetically beautiful, but also soft and fragrant with the natural scent of persimmon.
Step 3: Peel and slice persimmon
After washing, the persimmon will have its outer skin peeled off by professional farmers in the Cau Dat area (where is the cradle of the persimmon variety and specializes in producing flexible persimmon) and then depending on the purpose of production. Persimmons are kept whole or sliced and dried. This will determine the drying time of the product, so you need to consider it to suit your production facility.
The persimmon is cut in half before blanching. Do not cut too thin because when the drying process is completed, the product may become hard and hard, not meeting the toughness of dried persimmons.
Step 4: Perform drying persimmon
Arrange the processed persimmon slices into each drying tray of the cold dryer. Be careful not to stack the persimmons on top of each other as this will hinder the process of heat exchange and moisture evaporation as well as air circulation so that the persimmons can dry as quickly as possible.
The persimmon drying temperature on the freeze dryer is customized from 20 to 65 degrees Celsius. The freeze drying time depends on the technical requirements for processing dried persimmon. Drying time and moisture reduction are well controlled by the intelligent control process on the cold dryer to ensure that dried persimmon products are always delicious, flexible and retain their original flavor and color.
Step 5: Pack and label dried persimmons
Dried persimmons are often classified into sizes and packaged into 500g bags before distribution to the market. During the packaging process, we use a specialized vacuum machine for dried persimmons. Products are labeled with brand labels when brought to market. The packaging has the production date and expiration date on it. Please remember to pay attention to the expiration date.
