In the present invention, a vacuum dryer using isopropyl alcohol vapor, including an outer bath, an inner bath, a main water supply line, a supplementary water supply line, an inner bath drain line, and an outer bath drain line, is provided. After cleaning the inside of the vacuum dryer, the inner bath is filled with the supplied deionized water and the deionized water is continuously overflowed. Then, the semiconductor substrate is loaded into the inner bath of the vacuum dryer to which the deionized is continuously overflowed. The loaded semiconductor substrate is dried by supplying the isopropyl alcohol vapor to the inner bath into which the semiconductor substrate is loaded.

The vacuum dryer of claim 2, wherein the supplementary water supply line and the main water supply line are connected to each other and to the inner bath so as to switch between the main water supply line and the supplementary water supply line.

The vacuum dryer of claim 6, wherein the supplementary water supply line and the main water supply line are connected to each other and to the inner bath so as to allow switching from the main water supply line to the supplementary water supply line.

A vacuum dryer is obtained by improving the above-mentioned IPA vapor dryer. In the drying method in which the vacuum dryer is used, the amount of IPA consumed is less than that of the IPA vapor dryer. Therefore, it is possible to reduce the degree of environmental pollution caused by the IPA. Also, it is possible to obtain an excellent drying effect regardless of the presence of the pattern. However, as the semiconductor device is further integrated, recontamination by particles in the drying method in which the vacuum dryer is used comes into question. Therefore, a method of drying a semiconductor device by which it is possible to more stably prevent recontamination by particles is required.

There are certain parameters that you must always keep in mind while choosing a rotary clothes dryer. Take a look at some of the factors that you must keep in mind while selecting the perfect rotary clothes drier for yourself.

• Quality of the rotary clothes dryer: the quality of the product should be your top most concern. You can go ahead and invest in something that is of very good quality. Your outdoor rotary clothes dryer will be exposed to all types of weather. It should be strong enough to withstand the harsh weather conditions. Check the metal frame of the product. Also see that it is coated in dense paint.

• The size: you will find these in various sizes, 60 meters and 30 meters are the most common sizes possible. If you want to use it for your entire family, then 60 meters is the ideal size. Otherwise, 30 meters is suitable for those who have to use it for hanging laundry of two people. The bigger the size of the rotary clothes dryer, the more space it will consume.

• Is it portable? We do require the space in our yards for barbeque and as a playground for kids. During such times you need to remove it and clear the space that the rotary clothes dryer was occupying. However, if the garden space is big, you need not move it anywhere for making space.

• Can it be folded? Many rotary clothes dryers can be folded. Many of us prefer to buy one of this kind in order to utilize the space which otherwise would be occupied with the clothes dryer and to also protect it from unnecessary exposure to the weather.

• The color of the dryer: several companies manufacture rotary clothes dryer in many colors. You can choose the color of the dryer which you like the best.

• Breeze brakes: you will find some rotary clothes drier with breezy brakes. These special dryers are useful in areas which are prone to strong winds. The line of the dryer is prone to rupture when the wind is too strong. The breeze brakes keep the winds in control and prevent the clothesline from all possible damages.

• The gear system: the gear system is needed in those clothesline which are placed in areas with poor wind movement. The gear functions by upholding the clothesline to the wind so that the clothes on it dry up fast.

• Sheet separator: these are placed on massive size rotary clothes dryer. Due to presence of the sheet separator, the clothes dry up fast.

• Coat hooks: you can get rotary clothes dryer with coat hooks. It will be easy for you to hand your coats so that they dry up fast.

• The process of installation: installation of the rotary clothes dryer may be a heck. So choose a company which will install the object for you.

From work boots to ski wear to cold water rescue suits and beyond, there are certain types of apparel that have a predisposition to getting wet. Furthermore, items such as these don't let themselves to being dried by tumble style dryers. The trick is in finding clothes dryers and boot dryers that were created for the very purpose of drying just such apparel, and luckily there is just such a solution: residential and commercial direct air dryers from Williams Direct Dryers™.

Our electric wall mount and portable dryers set the standard because they use forced warm air, the most effective form of drying there is. Warm air holds more vapor than cold air, enhancing the rate of drying our electric dryers provide. And because these machines can operate equally in cooler conditions there is no end to the people and industries that can use them. In addition, nearly all of our dryers offer the option of warm or ambient forced air drying at the flick of a switch.

Our boot dryers are hand made from welded metal construction and feature a powder coated finish. Williams Direct Dryers™ are the only dryers that use technology that dries from the toughest part of the boot to dry, the toe, backward. Also, our dryers do not inject a disinfectant into the fabric. Ozone is commonly used for this purpose but is both a pollutant and harmful to humans and corrosive to fabric.

From private residences to ski resorts, and 5-star hotels to NASA, the United State and Canadian military, law enforcement and fire and rescue services, the list of those who depend on our direct air dryers is impressive indeed.

The invention pertains to the field of direct dryers for industrial and commercial use, and in particular to a continuous flow fluid bed dryer. Such dryers are typically used for the drying of delicate free flowing products such as certain grains. Such grains tend to suffer degradation in dryers having rapidly moving mechanical parts that interact with the product. The fluid bed dryer typically has a drum or housing with a plenum region beneath a product drying region and separated from it by a porous screen. Heated air is introduced into the plenum. Particulate matter to be dried is "fluidized", that is it is suspended above the screen on the heated air rising through the screen. This produces a turbulent mixing action between the target product and the air resulting in the drying of the product without damage to it. The screen openings can be canopied to direct air flow and deter clogging of the screen openings. In such dryers the heated air flow is used both to dry the product and move it along the dryer to a discharge. The amount of air needed to fluidize the product is often greater that the amount of heated air needed to dry it. This results is wasted heat since the amount of heated air supplied is a function of the amount of air needed to fluidize the product.

A continuous flow fluid bed dryer for drying of particulate product, comprising: a dryer housing having housing walls defining a drying chamber and a plenum chamber located beneath the drying chamber; a product inlet to the drying chamber and a product outlet from the drying chamber; a porous screen separating the drying chamber from the plenum chamber between the product inlet and the product outlet; an heated air inlet to the plenum chamber for introduction of heated air for movement through the plenum chamber to the drying chamber; a rotor shaft mounted for axial rotation in the drying chamber, and means for rotation of the shaft; a plurality of paddles connected to the rotor shaft for movement about a path whereby the paddle ends sequentially sweep over the surface of the screen to move product away from the screen permitting a rush of heated air into the drying chamber from the plenum chamber;

There is a momentary fluidizing of the product at that locale resulting in mixing and drying of the material. The advantages of a fluid bed dryer are realized without fluidizing the entire bed at once. Paddle movement is slow and gentle. Product moves forward to the discharge opening. Since the entire bed is not fluidized, the particles are not classified by weight or size. Varying size particles remain mixed together. The high sidewalls of the drying chamber leave a large upper area where air flow is considerably lessened. This avoids separation of the lighter and smaller particles from the bed.
