Dryer for Pears, How Do Pears Dry Out?

The pear, also known as the snow pear, gets its name from the fact that it is as white as snow. Quite a common fruit, in fact. The Compendium of Materia Medica states that "Pears are beneficial and have a smooth downward movement." Pears provide a smooth movement downward.

In addition to its medical properties, it can alleviate wind heat, moisten the lungs, calm the heart, reduce phlegm, diminish fire, and detoxify the body. Pears have been shown to offer the benefit of moistening the lungs, removing dryness, easing cough and resolving phlegm, nourishing blood, and producing muscles, according to study conducted in the medical field. As a result, it is useful for patients who have acute tracheitis and upper respiratory tract infections and who have symptoms such as dry throat, itching, soreness, hoarseness, thick phlegm, constipation, red urine, and the evacuation of phlegm.

It is excellent for individuals who suffer from hypertension, hepatitis, and liver cirrhosis to consume pears on a regular basis because pears provide the benefits of decreasing blood pressure, nourishing yin, and eliminating heat. With a flavour that is sweet and a nature that is cool, it has the ability to generate fluids and moisten dryness, clear heat and phlegm, nourish blood, and generate muscles, making it particularly appropriate for consumption during the autumn season. There are a few different ways to consume pears: fresh, steamed, and in soup and broth. Cangxi snow pear, on the other hand, is a cold-natured fruit that should not be consumed in large quantities at once. These individuals should avoid eating an excessive amount of food, particularly those who suffer from spleen and stomach deficiencies, cold abdominal pain, and blood deficiencies.

The procedure of drying the snow pear

During the first stage of the drying process, the temperature of the drying room is maintained at 70 degrees Celsius, and the snow pear is allowed to dry for a period of one hour. Drying takes place for two to three hours at a temperature of forty to forty-five degrees Celsius in the second stage of the process. As part of the third stage, the temperature of the drying room is maintained at around 50 degrees Celsius for a period of fifteen hours. As part of the fourth step, the temperature of the drying room should be kept between 55 and 60 degrees Celsius for a period of eight hours.

An explanation of how the snow pear dryer operates

The snow pear dryer makes use of the inverse Carnot principle to absorb the free heat in the air by inserting a small amount of electric energy and transferring it to the drying room (input 1 kilowatt hour of electric energy can generate 4 kilowatt hours of electric heat energy). This helps to raise the temperature of the drying room, which in turn works in conjunction with the corresponding dehumidification and dehumidification equipment to achieve the desired drying of the material.

Snow pear dryer's application field of application

Along with drying food, agricultural and sideline products, fruits, traditional Chinese medicine, wood, tea, spices, marine and aquatic products, and other items, the snow pear drier can also dry other things.

Dehydration procedure in a fruit drying chamber of the box type

Through the use of fruit dryers, the majority of the dried fruits and preserved fruits that are available for purchase on the market have been dried and processed. The drying process is also very important in order to obtain good results while drying fruit. This is in addition to the fact that selecting proper equipment is essential. In the following paragraphs, I will explain the drying process that fruit dryers go through:

Place the fruit slices in an even layer on the tray that is located in the drying room, making sure that they are not stacked too high, and then move them to the drying room so that they may dry. The sophisticated touch screen allows you to set the temperature as well as the time. You have the ability to adjust the temperature of the air energy heat pump dryer to anywhere between 10 and 75 degrees. A temperature that is too high at the beginning should be avoided in order to prevent the rapid loss of surface water and the inability to separate the water that is contained within. Because of this, the temperature for the first stage is set to forty degrees, and the drying time is equal to three hours. A temperature of fifty degrees is chosen for the second stage, and the drying process takes five hours. After the allotted time has passed, the machine will cease working automatically, and the dried fruits will be wrapped.

Generally speaking, the process flow of fruit drying machine processing can be broken down into the following steps: picking, cleaning, peeling, nucleating, cutting, pickling, positioning the plate, drying, and packaging.

1. Select fruits that are fully ripe and full of flesh. In general, ripe fruits have a taste that is considered to be rotting; therefore, it is preferable to select fruits that are 80% ripe.

To eliminate impurities and dust from the surface of fruits, utilise bubble cleaning equipment. After that, proceed to execute peeling, nucleating, and cutting operations on the fruits.

3 Prepare the sliced fruits by marinating them in accordance with the market need.

On the material tray, arrange the pickled fruit slices or strips in an even and regular manner. After that, transfer them to the fruit drying room so that they can undergo the drying transformation.

The process of drying In fruit drying, processing is an essential step that plays a significant role in determining the overall quality of the fruit that is dried. Preheating, drying, ripening, and shrinkage are the four steps that are typically identified as being the most significant in the process of drying fruit.

Preheating: For a half an hour, set the temperature to around 35 degrees Celsius.

During the drying process, the temperature is raised from 40 to 55 degrees Celsius, with each increment of 5 degrees Celsius. The duration of the drying process varies according to the type of fruit being dried and the requirements for drying it. During the early stage, it is possible to remove a marginal quantity of moisture, and during the later stage, it is possible to increase the amount of moisture that is removed. About six to twelve hours are required to complete the stage.

The process of saccharification, which is also known as maturation, occurs when the fruit itself has a high sugar content. Because of the high amount of sugar that it contains, water is difficult to evaporate. As a result, it is essential to raise the temperature to around 55 to 65 degrees Celsius for a period of time ranging from two to four hours, and to ensure that dehumidification is performed at the appropriate time.

The internal moisture content of the fruit is quite low at this stage, and the appearance has become stable in a shrinking state. This is referred to as the beginning of the shrinkage process. On the other hand, the hydration levels within the fruit are not uniform throughout. It is possible to use it continually at a temperature of 55 degrees Celsius and allow it to dry for two hours. At the point where the internal moisture content reaches the required level, the drying process can be finished in its entirety.

In order to avoid the fruits from becoming spoiled or regaining moisture, it is important to package them in a timely manner.
