Why is the drying room for making raisins built on the hillside?

The temperature difference is slightly larger, the ventilation is good, the humidity is low, and it is suitable for raisins to dry.

Raisins are the fruit of grapes that are dried in the sun or in the shade. Grapes are also known as grass dragon balls.

Rose apple. It is mainly produced in Xinjiang, Gansu, Shaanxi, Hebei, Shandong and other places. Harvested in late summer and early autumn, fresh or dried for later use. Raisin meat is soft, sweet, and nutritious.

The temperature difference is slightly larger, the ventilation is good, and the humidity is low.

Architectural construction. The raw earth buildings for drying raisins are all civil structures, generally with a flat-roofed rectangular pattern, and the walls are made of earth blocks, leaving many square flower holes to facilitate ventilation and prevent direct sunlight from shining on the hanging grapes. A number of "hangers" are set up on the wooden rafts of the drying room, which are fixed with branches, iron hooks or hemp ropes to hang the grapes.

The pylons should be about half a meter away from the ground to facilitate ventilation and sweeping of fallen grapes.

How to make raisins:

1. Selection of raw materials: Dried grapes should be selected with thin skin, plump and soft flesh, beautiful appearance and high sugar content. The fruit should be fully ripe, but not too ripe.

2. Cut the skewers: After harvesting, cut off the fruits that are too small and damaged, and cut the fruit bunches that are too large into several small skewers, and lay a layer on the drying plate.

3. Soda immersion treatment: In order to speed up drying and shorten the evaporation time of water, lye treatment can be used. After the raw material is soaked in alkali, it is immediately rinsed in clean water.

The drying time of the fruit after maceration treatment can be shortened by 8 to 10 days. When drying white raisins, it is also necessary to smoke sulfur for 3 to 5 hours.

4. Exposure: Put the grapes into the drying tray and expose them to the sun for about 10 days, and in sunny weather, the total drying time is about 20 25 days.

5. Softening: Stack the fruit bunches for 15 to 20 days to dry them evenly, and remove the fruit stalks at the same time, which is a finished product.

6. Packaging: Raisin packaging is divided into two types: cloth bag packaging and wooden box, cloth bag is divided into 50 kg or 25 kg, and wooden box is generally 25 kg.

The drying room for drying raisins has regular holes and presents the characteristics of transparency and simplicity. In Turpan, people often see a very unique kind of house on the side of the road, which is made of adobe on all four walls, and the walls are densely covered with air holes, and the larger houses are about two stories high.

This is the house where the raisins are dried, that is, the house where the raisins are dried.

Features of the drying room

Turpan grape drying house as a Uyghur.

The products of people's production and labor condense the wisdom of the working people, and also provide an inexhaustible driving force for the development of local grape culture. In the process of urban construction and planning, the construction materials of the drying house have been developed from the original raw soil to clean and reusable red bricks.

The dense regular holes in the grape drying room are transparent and concise, and the environmental protection of the materials, the integrity of the space, and the duality of functions all reflect its unique architectural style.

In the drying room, there are purlins with thick bowls every half meter or so on the roof. On each purlin, there are finger-thick wooden branches, which are wooden hooks for hanging grapes.

When the grapes are ripe, people hang fresh grapes from top to bottom on wooden branches, and after the whole hollow drying room is full, the door is closed, and the hot air of the Turpan Basin blows in through the pores.

After a month or so, the fresh grapes will turn into raisins.

The drying room is designed as a flat roof, and the honeycomb number is Zheng-shaped transparent wall, because China's Turpan land rent area is deep inland, and precipitation is scarce

Therefore, c

<> raisins are a favorite snack for many people, with a sweet and sour taste, 15 times more iron than fresh grapes, and a variety of minerals, amino acids and vitamins. But when most people eat raisins, they rarely wash them, and they just buy them and eat them directly, is this practice correct?

In fact, this way of eating is wrong, and raisins should be cleaned before eating when they are bought home. Because raisins are dried in the sun or natural shade, there will definitely be some dust and bacteria attached to the surface of the raisins in this process, and the invisible germs and parasites are also terrible, so it is recommended that friends wash the raisins and eat them with confidence.

However, many large enterprises now use manual drying methods to make raisins. In the supermarket, you can see that some raisins are bagged, and the packaging bag indicates that they are ready to eat when they are opened.

For the sake of health, it is recommended to wash the raisins on other stalls before eating. So how do you clean raisins? The fine washing method is to add some starch in warm water and mix well, and then put the raisins in and stir a few times by hand, the starch has an adsorption function to adsorb the dirty surface of the raisins, and the washing time should not exceed 3 minutes, and finally you can eat it after water.

It is good to grab a small handful of raisins before eating them every time, because the washed raisins are difficult to store and the taste will deteriorate.
