Is connected to the suction fan 12a. Each dust removal device 42a,
The operation of 42b and 42c is controlled by the operation control unit of the dryer according to predetermined conditions.
【００２３】このように構成することにより、排塵部の
高さ寸法を抑えて機体の設置条件を緩和するとともに、
乾燥運転の条件に応じて効率的に小電力で排塵すること
ができる。たとえば、張込量が多くて乾燥速度が速い場
合に循環回数の減少による除塵比率の減少を抑えること
ができる。With this configuration, the height dimension of the dust-exhausting portion is suppressed to ease the installation conditions of the machine body, and
Dust can be efficiently discharged with a small amount of power according to the conditions of the dry operation. For example, when the amount of swelling is large and the drying speed is fast, it is possible to suppress the reduction of the dust removal ratio due to the reduction of the number of circulations.

Shown in. As an example in which the drying rate setting, the swelling amount setting, and the initial moisture value are combined conditions, the condition category A of the drying rate setting is 6 steps, the condition category B of the swelling amount setting is 3 steps, and the initial moisture value condition category C Are three levels. Condition category A for drying speed setting
Introduces a weight of 1 to 6 at each of the stages of "low speed", "low speed", "normal", "high speed", "high speed", and "high speed". The condition classification B for setting the amount of stake-in introduces weights of 1, 3, and 5 in each stage of “less than 3”, “3 or more and less than 6”, and “6 or more”. Condition category C of initial moisture value is "25% or more"
1 for each stage of "less than 25%, more than 20%" and "20% or less"
Introduce weights of 3,5.

Next, by the condition check in S3 and S4, if the sum A + B + C of the weights of the corresponding condition categories A, B, and C is less than 4, S5.
If the dust collector is 1, 4 or more and less than 10, S6
If the number is 10 or more, 3 dust extractors are operated. With this control procedure, it is possible to control the operation of the dust removal unit according to a comprehensive evaluation based on a combination of conditions.

The set values are detected in S2a, S2b, and S2c in FIG. 11, and corresponding to S3 and S4, S3a, S4a in FIG.
The number of operating dust collectors is controlled in the same manner as described above by determining the conditions of S3b and S4b of 0 and S3c and S4c of FIG. Especially in the high-moisture area, it is difficult to remove the dust and the sized particles are likely to fly, so the operation of the dust extractor is limited, and by controlling so that all units are operated in the finished water area, the dust is efficiently discharged.
