Why will my colonists not use the nutrient paste dispenser?

The usual blockers are missing power, a blocked front interaction tile, food policy that forbids paste, an empty hopper, or putting the only meal source inside a prison-only room.

What can go in a nutrient paste hopper?

Use raw food such as rice, corn, berries, meat, milk, or eggs. Do not use hay, hops, or other rough plant matter.

Can prisoners feed themselves from a nutrient paste dispenser?

No. A warden feeds prisoners through the prison-side setup. Colonists should use the colony-facing side.

Build a Paste Dispenser That Never Jams

Fast build order, safe wall placement, no-surprises hopper rules, and two small planners for paste batches and grid margin.

Quick Solution

Research Nutrient paste after Electricity.
Build the dispenser into a wall with the front tile facing the dining room.
Keep the back on the freezer side and place at least one hopper touching it.
Fill the hopper with raw food such as rice, corn, berries, meat, milk, or eggs.
Keep the front interaction tile open, powered, and inside the pawn's allowed area.
Allow paste in food policy, then test with a hungry pawn instead of waiting for a cook cycle.

Best default: freezer on the back, clean dining room on the front, table within a short walk, and one fueled backup source for nights or eclipses.

Freezer and dining split blueprint — how to make nutrient paste dispenser rimworld — This is still the cleanest vanilla setup: hoppers stay cold in the freezer, the front interaction tile stays on the dining side, and the dispenser doubles as a wall piece.

Why It Won't Dispense

Power is on and the grid can carry 200W Front interaction tile is reachable and allowed Food policy allows nutrient paste At least one adjacent hopper has raw food The only meal source is not trapped in a prison-only room Paste is not getting hauled into a forbidden or unreachable spot

Everything looks clear. If it still stalls, draft a hungry pawn onto the front tile, undraft, and watch for the meal spawn at the mouth.

Prisoners do not self-serve. A warden handles prisoner feeding from the prison setup.
If pawns keep cooking instead, lower cooking priority or limit raw food access at the stove.
The front tile matters more than the dining room furniture. A blocked tile means no dispense.

No: hay, hops, and rough plant matter.
Default hopper rules also keep human meat and megaspider meat out unless you change the storage filter yourself.

Advanced Layouts

Double dispenser rush hour layout — how to make nutrient paste dispenser rimworld — **Double-dispenser line:** best when shift changes create traffic or when you are feeding a large worker block from one dining room.

Prison feed through layout — how to make nutrient paste dispenser rimworld — **Prison feed-through:** keep the freezer on the colony side, keep the prison on the other side, and let the warden handle feeding without opening the cell room.

1.6 Notes & Fast Answers

Core dispenser stats are the same on 1.6.4633: same build cost, same 200W draw, same 0.30 raw nutrition per dispense.
The late-2025 room-separation fix did not remove the classic freezer-wall build. It mainly cleaned up edge cases around separated rooms.
Use paste for workers, prisoners, and stability. Save fine or lavish meals for mood spikes, nobles, and pre-surgery comfort plays.
If you only build one dispenser, put it where colonists eat every day, not inside the prison block.

Fast rule: if a hungry pawn can stand on the front tile, sees an allowed food policy, and the hopper has raw food, the dispenser should work immediately.

Paste Planner + Power Margin Tool

Paste Batch Planner

Target paste meals

Raw input type

Paste uses a fixed build cost in nutrition, not a cook bill: target meals × 0.30 raw nutrition = required raw nutrition

Paste Batch Result

Set a meal target to get the raw food amount.

Raw nutrition needed6.00

Meal nutrition output18.00

Input units120 rice

Rounded surplus0.00 nutrition

Six 0.05-nutrition items make one paste meal.

Power Margin Inputs

Continuous load in watts

Solar generators

Chemfuel generators

Wind turbines

Batteries

Conservative rule: treat wind turbines as bonus headroom, not guaranteed night power.

Power Margin Result

Choose a load and power mix to see whether the dispenser stays stable.

Peak generation1000 W

Peak margin+550 W

Guaranteed no-sun output1000 W

Night margin+550 W

Battery-only blackout time32.0 h

Battery time at night deficitNot needed

One battery stores 600 Wd, which is enough for 72 hours at a 200W dispenser-only load.

Exact 1.6.4633 Build Values

Piece	Exact Value	Practical Use
Nutrient paste research	Base cost 400, requires Electricity	You can rush it early as soon as your power grid exists.
Dispenser build	125 steel, 3 components, Construction 5, WorkToBuild 2200	Cheap enough for an early colony, but not a day-one naked brutality luxury.
Dispenser size and placement	3 × 4, heavy support, front interaction cell offset on the mouth side	Plan the wall direction first. If the front tile is wrong, the whole room feels broken.
Dispenser power	200W constant draw	Budget it like a cooler: always on, always relevant during outages.
Per dispense cost	0.30 raw nutrition → 0.90 meal nutrition	This is why paste stretches raw food so hard compared with normal cooking.
Paste meal stats	Nutrition 0.90, FoodPoisonChanceFixedHuman 0%	You trade mood for consistency and raw-food efficiency.
Hopper build	15 steel, WorkToBuild 300	It is cheap enough to overbuild a little and keep refills easy.
Hopper filters	Raw food allowed; rough plant matter blocked; default excludes human meat and megaspider meat	Hay and hops are dead inputs. If a hopper is full of the wrong thing, the dispenser still looks "loaded" but gives you nothing useful.
Safe backup references	Solar 1700W peak, fueled generator 1000W, wind turbine 2300W peak, battery 600 Wd	Use the power tool above to see what your actual mix can cover overnight.
