Pollen and Propolis Collection Equipment

Pollen and propolis collection equipment is the set of tools that make use of the bees' natural behaviour to take clean pollen and propolis from the hive, and then to dry, clean, store and pack these products without spoiling them. The devices in the hive are simple; what really determines product quality is the post-harvest processing chain and hygiene. This page introduces the equipment chain for both products from start to finish and points you to the detailed pages.

Why are pollen and propolis equipment treated together?

Unlike honey, pollen and propolis are not collected with a centrifuge but by steering the bees' behaviour. A pollen trap scrapes the pollen pellets off the forager's legs at the entrance; a propolis screen transfers the bees' instinct to seal narrow gaps onto a removable surface. The two products have these things in common:

• A device in the hive, processing outside: the part in the hive is cheap and simple; post-harvest equipment such as dryers, freezers, sieves and containers determines quality.
• Food eaten directly: both are eaten unprocessed or minimally processed; so food hygiene and residue control are even more critical than with honey.
• Cost to the colony: a pollen trap reduces the colony's protein intake; a propolis screen can cause heat loss in the wrong season. The equipment is used while monitoring colony strength.

What equipment is used for collecting and processing pollen?

The pollen production chain runs in this order: trap → daily collection → drying or freezing → cleaning → storage and packing. Each link has its own equipment.

Pollen trap

A pollen trap consists of a perforated plate the bee must pass through when entering the hive, with a collection drawer beneath it that the bees cannot reach. The holes are about 5 mm in diameter; as the bee passes, some of the pellets are scraped off and fall into the drawer beneath a fine wire mesh. There are three main types: the entrance (front) trap fitted to the hive entrance, the bottom trap that replaces the floor, and the top trap placed between boxes. A good trap has a drone exit, a rain shield and a way of switching the trap off.

Dryers, freezers and cleaning devices

• Pollen dryer: a thermostatic cabinet with a fan and wire-mesh or perforated trays. The drying temperature should not exceed about 40 °C; high heat damages colour, aroma and nutrients.
• Freezer: fresh pollen can be stored by freezing it directly; dried pollen is also kept in the freezer for a while to deal with wax moth eggs.
• Sieves and air-flow cleaners: separate bee parts, wax fragments, dust and broken pellets from the dried pollen. Small operations use hand-shaken sieve sets; large operations use vibrating sieves and machines with blowers.
• Moisture measurement: a simple hand test or a moisture meter to tell whether drying is sufficient.

What equipment is used for collecting and processing propolis?

The propolis chain runs in this order: screen (trap) → freezing → flexing to release → cleaning → storage → extraction if needed.

• Propolis screen or slotted plate: usually made of flexible, food-grade plastic; placed on top of the top bars, under the inner cover. The bees fill the narrow gaps with propolis.
• Hive tool and scraper: scraping is done from frame lugs and box edges; practical, but the product may carry wax, wood shavings and paint.
• Food bags and freezer: propolis, sticky at room temperature, becomes brittle in the cold; when a full screen is frozen in a bag and flexed, the propolis flakes off.
• Cleaning and storage: a plastic spatula, gloves, a clean tray and airtight, dark-coloured containers.
• Extraction equipment: glass containers, strainers and filling tools for processing raw propolis with food-grade alcohol or other solvents; this step is subject to food legislation.

Which equipment is needed at which scale?

What should you look for when choosing equipment?

• Hive fit: the trap and screen must fit the dimensions of your hive type (Langstroth, Dadant, etc.) exactly; if gaps are left, the bees bypass the trap or build wax over it.
• Food-grade materials: every surface in contact with the product must be stainless steel, food-grade plastic or glass; painted or impregnated wood must not touch the product.
• Cleanability: designs that can be taken apart and washed, and that don't collect pollen and dirt in corners, are preferred.
• Heat control: check with a separate thermometer that the dryer's thermostat holds the true temperature.
• Workflow: the number of traps, dryer capacity and freezer volume must match; taking more pollen than you can collect and process spoils the product.

Residues, hygiene and colony health

Pollen and propolis can retain agricultural pesticides from the area where the bees fly, and fat-soluble residues of treatments applied in the hive. During varroa or any other treatment, traps and screens are removed from the hive; product from the treatment period is not sold. The trap or screen from a hive where disease has been seen is not moved to another hive.

In Türkiye, bee products fall under the Turkish Food Codex Communiqué on Bee Products. Under the communiqué, fresh bee pollen is kept at +8 °C or below until it reaches the consumer; dried pollen is exempt from this rule. A beekeeper who intends to sell would do well to find out the current legislation and registration obligations from the local agriculture authority.

Common mistakes

• Starting to collect pollen without a dryer: pollen in the drawer can go mouldy in a day.
• Trying to remove propolis from the screen at room temperature: the propolis stretches and the screen tears.
• Mixing scraped propolis with screen propolis: the value of the clean batch drops.
• Forgetting equipment in the hive during a treatment period: the whole batch ends up with residues.
• Storing the product in a transparent container in the light: colour, aroma and volatile compounds are lost.
