NUT CREAMS AND PASTES FILTRATION

Nut‑based creams and pastes are demanding products to handle: they are dense, creamy and often abrasive, and they may contain residual particles from grinding or roasting stages. Filtration is needed to remove these unwanted fragments and other contaminants without altering the product's rheology or introducing air and turbulence. A suitable vibrating sieve must therefore combine gentle handling with reliable separation, even at relatively high viscosities.

MLT Cuccolini addresses these requirements with the VSB vibrating sieve range, specifically dedicated to nut creams and pastes filtration. VSB machines operate at low frequency with calibrated, gentle vibration, allowing the product to pass rapidly through the mesh without causing splashing, foaming, air bubble embedding or resonance on the screen. This controlled motion protects the integrity of the mesh and ensures a stable, continuous flow even when dealing with thick, highly viscous products.

Thanks to their optimised design, VSB sieves enable product to pass through the selected mesh without the need for mechanical pushing devices. The combination of low‑frequency motion and appropriate screening surface is enough to promote a steady flow, avoiding additional shear or mechanical stress that could negatively affect product structure. This simplifies the line configuration and reduces the number of components in contact with the product.

A key feature of the VSB range is the use of special sealing systems developed by MLT Cuccolini to prevent any product leakage from the machine body. These seals confine the product to the zones where it is meant to pass, limiting residue build‑up in dead areas and making cleaning operations faster and more predictable. As a result, cleaning cycles can focus on the natural product flow path, helping producers maintain hygienic conditions with reduced downtime. Moreover, the standard mechanical mesh tensioning by MLT Cuccolini ensures fast cleaning of the mesh fixing areas avoiding the risk of mould creation.

Because the VSB solution builds on the correct selection of vibration parameters for this specific category of products, the resulting machines remain mechanically simple while delivering high throughput on dense, slow‑moving creams. This balance between simplicity and performance is particularly valuable for lines processing a variety of nut bases, where consistent filtration quality, ease of integration and straightforward maintenance are all essential.

Choosing MLT Cuccolini VSB vibrating sieves for nut creams and pastes filtration means combining gentle product handling with effective removal of grinding residues and other contaminants. Producers gain more consistent texture and quality in their spreads and fillings, better protection of downstream pumps, heat exchangers and packaging equipment, and shorter cleaning times thanks to optimised sealing and internal geometry.

For both new installations and upgrades of existing lines, MLT Cuccolini supports plant designers and end users in defining the most suitable VSB configuration, matching vibration settings, mesh size and layout to each specific nut cream or paste application. VSB is suitable for the filtration of creams and pastes based on hazelnuts, almonds, pistachios, pecan nuts, macadamia nuts, peanuts, chestnuts and cashews.
