Smart device dry noxious component

Datetime:2015-4-1 14:13:30   Hits:1259

  Pharmaceutical industry attaches great importance to research and development, the purpose is to find a new active ingredient. And more and more components identified are toxic, so the operating personnel in direct contact with these drugs is very dangerous and should be avoided. As a result, to take measures to prevent drugs and other substances in contact is required.

  Before nature has not yet been measured, vacuum drying oven is a flash drier new active ingredient wise choice because it has a number of advantages. This drying method can protect the bulk material recovery, there is no product residue. In order to avoid massive active ingredient is decomposed into small particles, Pink spray drying apparatus of the patent on the spacer means disposed on a mounting flange. Because the active substance is the result of "reactive" or "centrifugal separation" These steps before reaching the filter stage, so the filtration process step (pressure filtration) incorporated into the system to make the integration of the previous step is meaningful. This complex process unit must have the following features:

■ The operator must be protected against any toxic substances or infringement of human contamination. Protective clothing and protective measures as simple as different anti-virus function of the system is the result of the assessment and testing and certification.

■ sensitive high concentrated product must be isolated from the external environment, in order to ensure quality. In the above described system, the products are usually stored in an internal controlled conditions environment.

■ When small batch, no product loss is very important, because these materials are generally expensive and are highly toxic.

■ design of the entire system must meet the GMP requirements.

  All surfaces are smooth and the system can be observed at the same time must be easy to clean, to avoid cross-contamination. System consists of the following three process units:

■ slurry filtration device

■ isolation device

■ vacuum drying oven

  In order to achieve security purposes, the entire window system are bolted on the isolation device, vibration fluidized bed and only when the main routine surveillance can be opened. The system's unique feature is that it can be operated from the front and rear two positions. This makes it easier to operate the slurry filtered.

  Located in Scraper dryer drum instrument reinforced District oval grip flange so that workers can move the entire device. Boyer door welded on in the removal of excess material or tools easier. The system has three rapid switch ports can be used to control the product plus materials discharged. La Calhene system allows the operator to open the sealed containers or sealed implemented. System for the feed conduit disposed between the outer cover, mud filters and isolation means wall.

Mud filter integration

  Mud filter mounted on the isolation device, can withstand the maximum pressure of 3bar. Disc dryer product is placed in the filter chamber (chamber located inside the filter). Roof is manually operated, two air springs on which to make opening and closing operations are relatively easy to implement. After binding and isolation device, the operation is easy to implement particularly important. Mud filter pressurized with nitrogen gas, liquid / volatile substances expelled from the filtrate.

  The filter medium will also affect the nature of the degree of filtration. After filtration is complete, open mud filter, the filter was placed on the remaining loading tray. In order to ensure that even the smallest hollow blade dryer product residue is not lost, the entire filter chamber can be removed from the filter and separator filter media can be constantly changing.

Drying stage

  Dish filled with filter material is placed in a drying oven. The splitter is located in the drying furnace is controlled to a minimum depth to allow operation easier. Based on consideration of ergonomics, in order to enable the operator to remove the plate from the drying oven does not seem too much trouble, I chose a very sophisticated design simple door for this purpose. In fact, the door is divided into two parts, which are the door on the aircraft wing alike, can go in a certain direction, it can also be rotated 180o, so that the operator can see the situation inside the device surface. The biggest advantage of this is that all the drying oven stove shelves are welded to the side and back panels, and the entire apparatus are no gaps or feed channel. All corners are smooth transition. This patent also has a drying furnace temperature distribution equilibrium (shelf temperature of 61 ℃) features, so no matter which operator to use a rack to dry products, the results are repeatable. After kiln drying, the carrier plate is removed from the drying oven. The dried product through a RPT port to the sealed container. The sealed container may be removed from the system, it is introduced into the system to another port of the RPT. After use, the carrier plate left on the shelf. To reduce weight, the rack separator is made of plastic, and can be placed easily in and out of the door by Boyer.

Cleaning system

  Two manual spray gun mounted on the left and right sides of the system for cleaning. Gun hanging on the top floor unit located on the bottom of the isolation hook, so they do not have any relationship with the usual system operation. Two drain isolation device located bottom surface, easy to clean after the liquid is discharged. All surfaces inside the furnace can be seen from the direction of the operator. Welded to a small shelf mounted on the front portion of the angle of inclination, to facilitate the flow of liquid after cleaning. Push-pull system has two filters, so do not open the unit, there is a band dryer equipment can replace the filter cartridge to work. Contaminated filter cartridge can be taken out by the port of the RTP.

  For security, isolation means there is overpressure limits. Exhaust outlet overpressure capability and exhaust related. The internal pressure was maintained between -50pa ~ -120pa. If a broken handle, fans can balance the increased gas flow and prevent the escape of toxic substances. The device can be manufactured using 316L stainless steel or nickel-based alloys. Surface roughness <0.4μm, meet pharmaceutical standards. Overall, for the toxic substances within a certain range of pollution-free production, this system is an excellent choice.
