Vertiblend Tower Blending Sequence

STAGE – 1 :

  1. Door in closed condition.
  2. Teas are spread / layered equally into all eight chambers.
  3. The blending starts from this stage.

 

STAGE – II  :

  1. Opposite Doors are opened by geared drive in automated sequence of 1 & 5, 2 & 6, 3 & 7, 4 & 8.
  2. While the opposite doors are opening the teas on the top start rolling downwards due to gravitational force and also bringing down the teas below.
  3. The inverted cone and bathes at level-2 do not allow the teas to spread out and control the drop. The teas settle down blended.
  4. Once all the tea from the chambers are discharged, the doors shut automatically and the next cycle of feeding begins. Thereafter, the blending cycle is continuous.

 

STAGE – III  :

  1. The Discharge valve is now opened and the blended teas flow through the discharge chute.
  2. The blended teas are collected in hoppers or bags etc.

Salient Features / Technical Specifications

Bag Filling System (Net Weigher)

Sequence of Operation

The filling sequence starts after the operator clamps the bag & a START input from via push button on the controller or foot switch. The controller automatically tares the gross weight to obtain a Net weight of zero. The material is then fed into the bag, a twin speed screw feeder controls the rate at which it is fed. The controller compares the actual weight with the target weight settings, when the Main/Coarse feed setting is reached the main feeder is switched to Fine feed & feeding continues in the Fine/Dribble feed mode. The material is fed in the fine feed mode until the Final Weight minus In-Flight value is reached, after which the Fine feeder is stopped. Once the feeding is stopped a settling time (adjustable time, varies from 500ms to 1 sec) is given after which the end of batch is signaled, automatically the Totalizer and Bag Counter is updated. A pneumatically actuated consolidation mechanism is used to consolidate the product in the bag.

 

Safety Features & Interlocks

1. Sensor is provided to ensure that the bag is clamped.

2. Screw Feeder is interlocked through the bag sensor; ensure material will be discharged only if the bag is clamped.

3. Double acting solenoids for bag clamping ensure that in case of power failure the bag remains clamped in its position.

 

User Friendly Features

1. No operator adjustments are necessary when changing to different capacities, soft touch keys on the controller select recipes.

2. Auto-In-flight correction and auto tare facilities are incorporated to maintain accuracy and to avoid frequent adjustments ensuring hassle free operations.
