Bakery Fillings & Flavour Dosing – Food Grade Peristaltic Pumps

Case Study Information

Enquiry

A bakery and confectionary goods producer contacted Castle Pumps looking for some pumps to help them move away from the manual handling of some of their ingredients, and upscale their production. There were two separate applications for which they needed solutions which Castle Pumps were happy to help with.

Firstly, they required a pump for transferring the thick and sometimes solid laden fillings of their doughnuts and apple fritters. The second model would be for the dosing of vanilla essence and other flavourings. Of course, this meant that one of the most important parts of their requirements were that they were food safe pumps.

Key challenges:

Capable of handling viscous, solid laden fillings without clogging

Ability to accurately dose specific quantities of the flavourings

Food grade approvals required

Solution

Equipment Supplied

Model: Boyser AMP 13/B Peristaltic Pump

  • Max Flow: 3.9lpm
  • Max Pressure: 8 bar
  • Fluid: Apple pulp
  • Orientation: Horizontal
  • Voltage: 230v
  • Inner Hose Material: Thermoplastic
  • Suction/Discharge: ¾” Tri-clamp
  • Certifications: FDA
  • Drive: Integrated inverter

For the doughnut and fritter filling, an AMP peristaltic pump with an inverter was supplied. The addition of the inverter allows the bakery to adjust the speed of the motor when used with the fillings of differing viscosities. For example, when pumping the more viscous jams, the motor speed needs to be slowed considerably compared to when transferring the apple pulp.

The beauty of the peristaltic pump design is that its inner tube is the only part that encounters the fluid, with no valves to clog or impellers to jam. This design means that the peristaltic pump can easily handle the apple chunks and stringy solids present within the fillings without damage or downtime to the bakery’s process.

Model: Boyser DSM Peristaltic Pump

  • Max Flow: 1.75lpm
  • Max Pressure: 2 bar
  • Fluid: Vanilla essence
  • Orientation: Vertical
  • Voltage: 230v
  • Inner Hose Material: Norprene
  • Certifications: FDA

When it came to the dosing of the flavourings, Castle Pumps specified a DS-M peristaltic dosing pump. This model has excellent accuracy even at low flow rates, making it ideal for handling small volume transfer and highly precise quantities.

For both models, Castle Pumps specified a food grade thermoplastic internal hose and tri-clamp connections for a smooth, non-contaminating pipework joint, ensuring that the pumps are safe for handling products for human consumption.
