Requirement & Challenges
The client was making coriander powder with the standard process in accordance with EU, US, Australian, Indian & Japanese food safety norms. The client had the requirement of sieving coriander powder after initial grinding as to remove oversize particles (not properly ground particles) & send them back for grinding.
The challenges while sieving coriander powder was common yet considerable! The first & and foremost issue was of screening efficiency, following other issues like lumps & agglomerate blinding & blocking the screen and higher percentage of oversize remaining of the screen for a long time increasing the load on mesh affecting mesh life.
The rigid physical characteristics of coriander powder are the prime reason that makes it difficult to sieve material. It contains a high level of moisture & oil presence is quite more, these make it adhesive to screen while sieving.
Due to oil & moisture presence, the material forms lumps become sticky and not free-flowing, these all tend towards screen blinding & blocking. Screen blockage is the primary reason for low screening efficiency.
Earlier, the client was using competitor made round sifter & faced
– Low screening efficiency.
– Screen blinding.
– Low throughput.
– High maintenance.
– Frequent cleaning.
Requirement
– Sieving machine with higher screening efficiency.
– System/arrangement that could help de-agglomerate the powder & ease sieving process.
– No or minimal manual cleaning.
– High output sifter
Solution
The client approached us as we are their register vendor. We have already given multiple Vibro, rotary & linear sieves for their other products such as chilli powder, turmeric powder & sugar.
Sivtek expert suggested running an onsite trial with Sivtek Vibro Separator® (84”) along with Mesh de-blinding Kit (Ball & tray tapping arrangement). 3 Days long trial was conducted & result were as expected.
The problem of less screening efficiency & output was solved. Due to mesh de-blinding kit lumps was de-agglomerate & adhesiveness on-screen was eliminated. Mesh De-blinding kit enabled free flow, making the screening process efficient.
The client agreed to the provided solution & ordered 3 no. of Sivtek Vibro Separator® with Mesh De-blinding Kit.
Results
After installing 3 no. of Sivtek Vibro Separator, the client sent a testimony stating, “Solution provided by Galaxy Sivtek has proven to be in beneficial to us. All the problems we were facing earlier have now been addressed & solved successfully”.
